The Wild Side of Beth Chatto Gardens: the WildSide walks of August

Two sets of WildSide walks this month, separated by two weeks, a fortnight that might just have seen the transition back to more normal weather. The first walks, in early August, were around a browned, crispy garden, where not a drop of rain had fallen for two months. Never before have I seen the water in the ponds without any flow between them: the spring-fed brook seemed dormant.

But clearly the garden was still producing insects. As I arrived early in the morning, feeding flocks of Swallows descended on it, a very reassuring sign that we are doing something (hopefully everything!) right. And a clear sign that autumn is upon us, an early autumn ushered in by drought, there were two Willow Warblers in subsong. Both these species are in freefall as breeding birds in Essex, Willow Warbler almost extinct, some of the losses we are seeing as a result of climate collapse, but their populations are at present maintained further north and those birds must pass through our skies on migration, so we can see places like ours as oases to enable them to migrate successfully. Although Willow Warbler undoubtedly bred with us in the past, this was my first definite record for the garden.

Two weeks later, the heatwave had broken. It had even rained, just a little, enough to freshen up the garden, start the process of regreening the lawns, if not dealing with the accumulated drought of the ages. The Swallows and Willow Warblers were still there, along with singing Chiffchaffs, rampaging family parties of Blue, Great and Long-tailed Tits, and Greenfinches feeding on seeds in the Reservoir Garden. To complete the woodland bird scene, there were Blackcaps, a couple of Treecreepers, and Great Spotted and Green Woodpeckers calling.

High summer is insect time. Usually. But the intense drought has made its presence known especially in the higher, drier parts of the garden. While hopefully we will not have lost many plants (if we have, we will take positive messages from it, and learn), certainly the floriferousness of the Gravel Garden, Scree Garden and Reservoir Garden is much lower than usual at this time of year.

So the insect epicentre has shifted to the Water Garden. Especially around the ponds, there were Ruddy & Common Darters, Brown Hawkers and, during the later walks, Migrant Hawkers. Remarkably, of those that came close enough to be sure, more than a half of them were Southern Migrant Hawkers, a new arrival in the UK over the last two decades. We have only a couple of records previously.

Blue-tailed Damselflies are still around the margins, but Willow Emeralds are now everywhere, often hanging from tree branches. This species too is relatively new to Britain, but it has now established as THE damselfly of autumn, often persisting to the start of winter.

Other insects were being attracted in vast numbers to the waterside marginal flowers, most notably the ten-metre stretch filled with the triumvirate of Bistorta, Rudbeckia and, at the back, Eupatorium, each providing vast nectar and pollen resources. The most noticeable insect on both visits was Tachina fera agg., a parasite-fly in swarms that I have never seen the like of before, anywhere. Whatever the reason for this proliferation, it is safe to say that the next few months will not be a good time to be a moth caterpillar! Female flies lay eggs on leaves, but when the egg hatches the larva senses the proximity of a caterpillar, burrows in, and devours the caterpillar from the inside…

In addition, Bistorta was feeding large numbers of social wasps (including the large Median Wasp), bumblebees, Bee-wolves and other insects, with predatory Hornets swarming among the wiry stems like sharks hunting through a kelp forest.

The flatter flower-heads of Rudbeckia supported a different supporting cast to the Tachina throngs: familiar butterflies and ladybirds…

… hoverflies and other parasite-flies…

… bees and wasps …

… and true bugs, here a nymphal Hairy Shield-bug, a small Nysius species (probably N. senecionis) and adults and nymphs of both British species of Stictopleurus, S. punctatonervosus being a new garden record.

And wherever insects gather, there are stealth predators waiting in the wings!

 

Elsewhere in the garden, particularly the stockbeds, other yellow composites such as Inula and Helenium  fulfilled a complementary role to Rudbeckia:

A final selection of insects from this month starts with Common Field Grasshopper, German Scorpion-fly,  Hairy Shieldbug and Rhododendron Planthopper.

Typical late-summer butterflies included Common Blue and Small Heath (with, sadly unphotographed, Clouded Yellow), while spangle-galls of the tiny wasp Neuroterus quercusbaccarum signify the start of autumn senescence.

And flies featured heavily everywhere, with Hornet Hoverflies, our largest and most impressive; variable bee-mimic Furry Droneflies; and the first Locust Blowfly of the year. The latter is believed only to breed inside locusts, and so to always be a long-distance wanderer to this country; indeed when we first found it a decade ago, it was only the third-ever Essex record. Since then it has become more frequent, and 2025 saw a record influx, including multiple records from the garden in July and August, perhaps fuelling the suspicion that in our warming, uncertain world, native grasshoppers can now act as a host.

As for the other highlights, the first walks were treated to the sight of a Hummingbird Hawkmoth sipping the Cirsium and a Wasp Spider nestled among the Catananche…

… while the later walks enjoyed the sight of Firebugs, now firmly established with us,  swarming all over Althaea cannabina in search of seeds to suck the juices from, and a Sand Wasp Ammophila sabulosa clearly nesting in the bee-bank, another new species for the garden and not at all common in Essex although it did colonise Chattowood a couple of years ago and the Meanwhile Garden earlier this year.

Always something exciting to see! If anyone wants to join one of my WildSide Walks, you still have another chance on 11 September, book here Courses & Workshops – Beth Chatto’s Plants & Gardens. And failing that we hope to be back next summer: who knows what weather, wildlife and worry  the predicted ‘Super El Niño’ will bring our way?

The Wild Side of Essex: Wivenhoe & the Colne, after the heatwaves…

It was the day after the first rain in North Essex for more than two months. But it barely touched the sides: the wild side of Essex was brown, crispy and drooping, droughted to the extreme by an unprecedented summer of heat. But still we persevered, slowly and steadily focussing on the minutiae of life, as well as the geology, landscape, history, estuary life and townscape: everything that makes Wivenhoe special.

For the first stop, we had only to walk 10 metres from our meeting point, into the Station Community Garden. There one of the overriding themes of the day started to evolve: the wildlife and human impacts of climate change. In this case, it was highlighted by the arrival of two new species from more southern climes in recent years: Firebugs and Hollyhock Weevils, both feeding on the garden Hollyhocks.

The evident interest of the group meant that I ransacked  my store of stories about these creatures and changes, and then I realised more than thirty minutes had passed! Clearly I had a very receptive audience to the bigger picture, keen on an amble not a ramble, and I adjusted my plans and expectations from the day, which proved the right decision given the scorched earth of some of the habitats further from town.

The next stage of the walk was along the cycleway towards Colchester, one of the earliest parts of the National Cycle Network to be created, part of Route 1 that now runs from Dover to Aberdeen. The fringing trees and scrub revealed all manner of biodiversity, hidden to all except those who stand and stare… Oak Mildew Erisiphe alphitoides coating the lammas leaves, galls of Blackthorn Mite Eriophyes prunispinosae and leaf-mines of the micromoth Ectoedemia heringella in Holm Oak.

Ivy flowers were just starting to open. These will soon be the richest source of insect food imaginable, steering our bees and butterflies into an uncertain winter, while the birds will be supported by wild fruits, such as sloes, blackberries and rosehips. Given the lack of summer rain, it seemed surprising that the fruit was swelling as much as it was.

Moving onto the Ferry Marsh sea wall, our first glimpse of the estuary. The tide was out but there were very few birds: a few Mallards, a fishing Cormorant, and fly-over and feeding  Little Egrets. And of course the gulls, mostly Black-headed along with a few Lesser Black-backs, one of the juveniles of the latter colour-ringed and presumably locally rooftop-reared.

Stunted Oaks on the sea wall featured an array of galls, including Knopper Galls on the acorn cups and Common Spangle-galls on the underside of some leaves, and one harboured a very striking form of Harlequin Ladybird.

One result of the drought was a near absence of flowers on the sea wall. There were a just a few flowering Bristly Oxtongues, along with Hoary Ragwort, typically a late-flowerer but now rushing headlong into seed.

The elevated position of the sea wall gave good views over the reedbed, although there was little to see or hear (it is that time of year), apart from a very occasionally singing Cetti’s Warbler and some Whitethroats, probably a family, keeping together with contact calls. Overhead, both Swallows and House Martins hawked for flying insects.

As soon as we went down to reedbed level, temperature and humidity increased, as did insect activity, including several hunting Migrant Hawker dragonflies. Flowering Teasel showed what a huge resource for late-summer pollinators its flowerheads can be, and the leaves of Dittander picked judiciously from above the dog leg-lifting zone provided a refreshing horseradish hit for all.

Estate trees showed the considerable value of many to native wildlife, as well as casting welcome shade. Swedish Whitebeam was in full fruit and will feed birds over the coming autumn, while its bark was a suitable substrate for lichens responding to reductions in air pollution that have been achieved in recent years.

Thence onto Wivenhoe West Quay, attractive re-use of a former port on one side, tidal mudflats and marshes on the other.

The mud had feeding Redshanks, a single Black-tailed Godwit recently returned from its Icelandic breeding haunts, and single Lapwing and Curlew, probably having bred rather closer to home in the moors of the north country.

And the tidal saltmarshes showed a fine range of salt-tolerant plants, including Marsh Samphire (or Glasswort), Sea Beet and Sea Purslane, the ‘desalination plant’ par excellence, together with the relatively newly evolved (through hybridisation and chromosome doubling) Common Cord-grass, on the marsh but also spreading down onto the mudflats.

After lunch (thanks to Sara at the Rose & Crown for allowing us to use their loos), we continued along the frontage of old Wivenhoe. Lovely gardens spilling over into the wild gave us Fennel and Rock Samphire, two more sets of scents and flavour, and Buddleia living up to its other name of Butterfly-bush with a couple of pristine, locally reared Painted Ladies as well as an assiduously feeding Hummingbird Hawkmoth, bobbing in and out of the camera frame. How long will it be before we stop referring to these as immigrants to Britain?

Wivenhoe waterfront is a palimpsest of overlapping histories, from fishing, ship-building, and ports to art and commuterland residential. But all these uses are set within the context of a tidal river, always a resource, on days like today benign, but on others a threat. Hence the reassuring presence of the Wivenhoe flood-defence barrier downstream…

Beyond the barrier, the highest line of the unconstrained tide was the location for Strawberry Clover, as lovely in seed as in flower.

Barrier Marsh failed to live up to its name, barely a blade of green grass to be seen, although making it easier top see the ancient trackway of the Chase, historic access for an otherwise landlocked parish to the resources and opportunities of tidal waters, along with the massive, perhaps up to 400 year-old, anthills on the probably never ploughed eastern ‘marsh’. From our sea-wall vantage point, raptors hove into view in the form of Buzzards and a pair of Red Kites, while a Kestrel remained stubbornly at rest atop a dead tree and a Green Woodpecker flew silently from anthill to abandoned, rewilded railway line.

By now the tide was flooding and the waders started to show their numbers, just one Avocet, a handful of Curlews, low tens of Redshank but maybe 400 Black-tailed Godwits, although sadly they chose to head to high-water roost on the other side of the estuary.

All that was left was to wander back through Wivenhoe. The Shipyard produced two of its specialities, stunted, trampled, droughted but seemingly very well settled Four-leaved Allseed and that ‘new kid on the block-paving’ Spotted Spurge.

The gardens of Queen’s Road gave us a tree-topping, ‘chick’-ing Great Spotted Woodpecker that held its high ground for several minutes, before we got back to our final two stops of the day. The ‘Old King George’ Oak still stands despite antipathy from Aviva and apathy from the Town Council; for now it is secure and cannot be felled as an interim injunction is in place. We are hopeful this will be confirmed at a High Court hearing we understand may be coming up…

And finally into the King George V playing field, the former front garden of the now-long-gone Wivenhoe Hall, introducing a new, useful word (‘quincunx’) for the Scrabble enthusiasts, and demonstrating just how parched the uplands have become over our unprecedented summer.

All in all, a very different Naturetrek walk. Unique in fact. We covered less than half the distance we usually do, but in the same time. Fortunately this particular wonderful group seemed to appreciate a gentle day of stories from and about Wivenhoe. Thanks to all!

 

#WildEssexWalks: an evening potter around Wivenhoe Barrier Marsh

It was third time lucky for our evening walk around Barrier Marsh and Wivenhoe Waterfront, postponed once because of extreme heat and once more through illness. Our third attempt with an eager throng of friends was still warm, around 24°C at 7pm when we set off, but a delicious, gently cooling easterly breeze made conditions very pleasant.

Starting at the Shipyard, our block-paving population of Four-leaved Allseed seems to be having an outstandingly successful year, seemingly impervious to extreme drought and chemical onslaught. First found here during the pandemic, its distribution is still expanding from its original haunts of south Cornwall and the Scilly Isles.

The saltmarshes have no showy flowers at the moment, at least until the Sea Aster comes out later this month, although Common Cord-grass is in flower along with Sea Purslane. The super-salty hit of the leaves of the latter, covered in the excretions from its desalination cells were a surprise to many. And Marsh Samphire was, as is typical of some forms at this stage of the season, shot through with succulent emerald.

The Sailing Club hedge was starting to look very autumnal, with sloes, hips and haws all filling nicely, surprisingly perhaps given that it has not rained a drop here for more than a month. These will of course become vital winter bird food, assuming the hedge is not attacked by the ‘tidy brigade’…

As usual, Strawberry Clover was looking magnificent along the extreme high tide line, and an interesting new feature, a microcosm of Orford Ness, has recently been installed:

Below the Barrier, the estuary widens and the local moulting Black-headed Gulls were joined by the first returning Curlews, plus Oystercatchers and Redshanks, some at least of which may be local breeders.

The seaward face of the sea wall was in places clothed with the grey, absinthe-scented leaves of Sea Wormwood, although it has yet to come into flower.

Crossing the grazing marshes on The Chase, it was, as everywhere, very parched, especially so on the tops of the numerous anthills illuminated beautifully by the slanting, setting sun.

Few flowers were showing apart from occasional Hairy Buttercups and patches of Creeping Thistles, on one of which Jude (of course!) spotted a beetle Anthocomus rufus, sometimes known as the Red Malachite-beetle, a species closely associated with coastal habitats. Although it appeared to be feeding in the flowers, it is primarily a predator of other insects, and so may have been searching rather than supping. And with the aid of our bat detector she also picked up the song of a Dark Bush-cricket. But nobody could hear it unaided…. we are all of a certain age!

Birds were few and far-between, just a calling Green Woodpecker and skulking Whitethroats and Reed Warblers in scrub and reedbeds respectively. That is until sunset, when the birds woke up, with Robin and Cetti’s Warbler singing and groups of Little Egrets heading down river presumably to a communal roost.

All that remained was to potter back along the Wivenhoe Waterfront in the glorious gloaming, buy a welcome cooling pint at the Rose & Crown, and settle down outside to watch and hear the first hunting Common Pipistrelle, as well as a remarkable chorus of House Crickets. From the bottom of Anchor Hill to Bethany Street, there were multiple singing males, many more than we heard last year, the first time we recorded them here. Instant transportation to the southern climes of Europe, and a thrilling, trilling end to a lovely walk!

The Wild Side of Beth Chatto Gardens: another dry July…

July: another month with almost no rain. The hum of summer pervaded the garden, if a little subdued especially in the heat of the hottest days. We’re in the midst of an unprecedented three successive heatwaves and almost continuous drought.

I had a busy month leading walks round the garden, but still found time to sit (in the shade!) and look. The full complement of dragonflies and damselflies has now emerged from the ponds with Willow Emerald, Southern Hawker, Ruddy Darter and Black-tailed Skimmer all flying.

Jersey Tigers have put on their now-expected emergence, a flurry of orange, black and white. Hard to believe that these have been with us for less than five years, having spread here under the influence of climate change. Hummingbird Hawkmoths have also been flying around the garden by day, feeding at Buddleja and other tubular flowers. This summer has seen quite a good arrival of these moths that have flown in from the continent; who knows when they will appear as permanent residents…

The same is true of Painted Ladies, ever-present this month following an influx earlier in the summer. Only Gatekeepers have been in larger numbers, feeding especially on Marjoram, alongside Common Blues, Brown Argus and other resident species.

Some other butterflies included Comma, Red Admiral and similarly familiar ones, including the first new-brood Brimstones, plus a few Small Tortoiseshells, very scarce this year presumably due to the relatively recent establishment of a new parasitic fly in this country.

Other new colonists over the past few years have also been apparent, such as Wasp Spider, Firebug (making more Firebugs, so we should be getting more!) and Rhododendron Leafhopper, only the second time I have seen this in the Gardens.

Parasite-flies have been very obvious, including Tachina fera and Eriothrix rufomaculatus, parasitic on larvae of other insects, and all helping bring natural balance to the garden.

Hoverflies have added their buzz to the soundscape, common species like Batman and Marmalade Hoverfly, together with less common ones like the Furry Dronefly, here in two colour forms mimicking different bee species, and Hornet Hoverfly.

As always there have been plenty of other things to enjoy as well, from Grey Herons around the Reservoir to Forest Bugs and Bee-wolves.

This was also the month we ran a moth trap over two nights, reported in detail here, and this alone added about forty new species to the burgeoning garden biodiversity list. But as always, casual observations added to the total. Several of these were leaf-mines and galls, a bit of a niche study …

… but there were others as well, from a couple of hoverflies (Scaeva selenitica and Eristalis horticola) to a jewel-wasp Pseudomalus auratus, a jewel-beetle Agrilus laticornis and the Viburnum Leaf-beetle.

As to what is in store for the rest of the summer depends largely on whether there is rain. But even if the drought persists, there will be things to see. There is always wildlife to see in a garden that prides itself as putting the right plants in the right place, right for us, the plants and for the insects that depend on them!

 

 

 

July Moth Morning 2026 at Beth Chatto Gardens

The second outing for our moth trap into Beth Chatto Gardens this year came just as the unprecedented third heatwave of the summer broke down, albeit not into a tumult of thunderstorms. The drought remained but the night temperature fell to a delightfully chilly 13 degrees. I had little idea what to expect as I opened the trap: it could have gone either way…

I characterised the previous trapping a month earlier as a qualified disappointment: the overall number of moths and species was lower than I hoped for given the heat of that particular night, and it felt the haul lacked a little in colour and the ‘big game’. The same was true this last weekend: it produced almost as many moths and almost as many species; plenty to see but just lacking a bit of spice.

At first view I was worried, though. Sitting on the outside of the trap was a Hornet. Even a small number of Hornets or other social wasps can cause carnage in a trap, but not this time. Just one Hornet outside, one and an equally predatory Common Wasp inside, and no obvious mortality. And the ‘big and beautiful’ were crown-pleasers: an Elephant Hawkmoth and two Oak Eggars…

Other ones distinctive in colour, pattern or posture included Rosy Footman, Black Arches, Scarce Footman and September Thorn…

Equally distinctive, though less obtrusive, were those hiding in plain sight and reliant on camouflage either as bark (Dark Arches, Iron Prominent) or bird poo (Lime-speck Pug, Least Carpet and Scorched Carpet)…

Another selection of macromoths helps complete the picture of their diversity and the delightful poetry of many of their English names: Large Yellow Underwing, Dingy Footman, Maiden’s Blush, Pebble Prominent, Twin-spotted Wainscot, Nutmeg, Spectacle, Lesser Broad-bordered Yellow Underwing and Sallow Kitten.

It is a simple fact though that even the macromoths are not always identifiable to species on external appearance. Some identicouples or moresomes can be specifically identified only by killing them and examining their unique genitalia, which of course is something we will not do. So the below must remain as Ear Moth (one of four possible species), Grey or Dark Dagger, and one of the three possible Common Rustics.

Turning to the numerous micromoths, most frequent were the several species of grass moth, along with small ermines of at least five species: Bird Cherry, Apple, Willow, Iceplant and Orchard Ermines.

Micros may (generally) be smaller but can be very attractive and/or distinctive, such as Agapeta zoegana, Ethmia quadrillella, Calybites phasianipennella, Water Veneer and Catoptria pinella:

Many moths are well-known as migrants to the UK from the Continent, and at this time of year a moth trap may well contain several specimens indicative of a recent immigration event. That was the case at the weekend, despite the fact that the breeze was northerly, with several Willow Ermines, Diamond-backs and Small Mottled Willows, along with single Silver Y, Dark Sword-grass, Rush Veneer and Rest Harrow, the latter until recently being considered a real rarity.

Hitherto migrant moths can and do sometimes establish breeding populations, and we had a selection of those too, with Tree-lichen Beauty, Cydia amplana and Plumed Fanfoot, first recorded in Britain in 1987, 1990 and 1995 respectively, and now likely to be breeding in and around the gardens.

All in all, the night’s haul amounted to about 350 moths of 96 species – see here for a full list and comparison with previous trapping at this site BC MOTHS TOTALS to July 26. This included more than thirty species new to the garden list: because we run the trap here only a couple of times a year, there is always ample opportunity to expand that list further! Running the trap in different locations and in different months would certainly add considerably to our overall biodiversity list.

As always, creatures other than moths found their way into the trap. Caddisflies are regular visitors, especially given the proximity of their aquatic breeding habitat, and included Glyphotaelius pellucidus and Mystacides azurea.

Another pond-dweller was the Supertramp Beetle Rhantus suturalis, one that is well known for dispersing at night and seeking out fresh ponds by the light of the Moon. A plant bug Phytocoris varipes was the first time we have recorded it in the garden, and the most dramatic element of the by-catch was a carrion-beetle Necrodes littoralis, a species best known from coastal strandlines, and indicative of the wondrous, largely unnoticed, flux of insects under the cover of night.

Our group also had time for a quick walk around the gardens and managed to see a couple of characteristic day-fliers, Jersey Tiger and Hummingbird Hawkmoth, along with a selection of butterflies, shield-bugs, dragonflies and damselflies.

*****************************************************

The trap was again pressed into action a few nights later, to prepare for a kids’ mothy session at the start of the summer holiday. With focus on experience rather than identification, we didn’t produce a full list for that event, but just appended new ones to the weekend trap results.

And what an experience it was for them, especially enthralled by the size of the Oak Eggar, the pattern on the Black Arches and the birch-twig camouflage of the Buff-tip. The latter was extremely compliant, allowing itself to be handed gently round all the little hands massed around the trap, one by one until even those who were initially scared had a go. And then it was released into safety, content in the knowledge that it might just have changed the life of one or more of the kids.

And remarkably, given that we had trapped only four nights’ previously, I found about 25 moth species that had not appeared in the trap on Friday night and, of those, nine were were completely new to the ever-expanding garden biodiversity list. Some of the absentees from the Moth Morning event were White Point, Gypsy Moth, Pale Prominent, Peacock Moth and Sharp-angled Peacock.

Hopefully the Moth Mornings will be back next summer, and after the joy of the kids’ moth event, I would love that to become a fixture too. Watch the Beth Chatto website events page for more details.

#WildEssexWalks: Lower Lodge in the grip of a heatwave

As is by now traditional, we organised a WildEssex walk in high summer around Lower Lodge nature reserve, near Wivenhoe. Lower Lodge is a lovely, flower -rich grassland site, mostly mown on a three- or four-year rotation by Colchester City Council, producing a diversity of habitat structure, from woodland, to dense scrub, to scattered scrub to open grassland. All components have their value, although the open grassland is especially diverse for both insects and flowers.

But we hadn’t planned on a summer like the current one. An unprecedentedly hot, dry summer with three heatwaves and droughts already, and it is only mid-July. So it was with some trepidation we set out onto the site to see what we could find. At least there were plenty of pollen- and nectar-bearing flowers, particularly Wild Carrot, Hogweed, Common Knapweed, Field Scabious, Creeping Thistle and the beautiful bicolored form of Field Bindweed.

From a distance there were a few butterflies flitting around, but I was stopped in my tracks at the very first Carrot umbel: Ectophasia crassipennis! A stunning parasite-fly that lays its eggs on unfortunate shield bugs before the fly larvae devour the bug from the inside. Slowly….

It is a species I know well from the Pyrenees that first reached the UK in 2019; it is now found widely along the south coast, but is only just starting to head our way. So far as I can ascertain there are only a couple of other records from Essex, one at Wrabness in the year of its first arrival and one last year that I found in Beth Chatto Gardens.

We then carried on on the parasite-fly theme, recording two more species, Tachina fera and Eriothrix rufomaculata.

What a great start and although individual numbers of most insect species were not high we kept on finding things of interest until the end of the two hours when the other absolute highlight performed as the very last insect of the walk. This was a Hummingbird Hawkmoth, always good to see and reasonably common this summer. But what was it doing hovering its way through, not over, the grass, avoiding the flowers, completely oblivious to us as it flew between us, and occasionally touching down? And then it twigged, ‘it’ was a ‘she’, she was laying eggs on the Hedge Bedstraw plants growing in the grassy sward. This is not a behaviour I have ever seen before, so our walk ended with me as excited as when we started!

Sadly, unless any larvae develop very quickly such that the next generation is out by early autumn, they are unlikely to survive our winter. But maybe, just maybe, a warm winter could allow it to succeed.

Other moths we saw during the walk were many and varied, from grass moths like Agriphila straminella (all very brown and flittery) to the stunning Brassy Longhorn (a specialist moth dependent upon Field Scabious, seemingly very scarce in Essex) and of course the Six-spot Burnets, resplendent in their black and red livery in the sun, whirring around, occasionally landing to feed, and some new emergers just drying out close to their vacated pupal cases.

Other flies feeding on the umbels included the hoverfly Chrysogaster solstitialis and lots of Flesh-flies, while sitting around on the leaves, either mating or on the lookout for insect prey were Kite-tailed Robberflies, alongside tiny sweat-bees Lasioglossum sp.

Another selection of insects feeding on flowers comprises a parasitic ichneumon wasp (the nemesis of caterpillars), Turnip Sawfly, a Knapweed Bug Oncotylus viridiflavus (for which there are only a couple of records east of Colchester), Hairy Shieldbug, Seven-spotted Ladybird, Thick-thighed Beetle and Hogweed Bonking-beetle. A veritable cornucopia of delights!

So among the insects that leaves just the butterflies. Gatekeepers were the most numerous, with just a few Meadow Browns, good numbers of pristine Painted Ladies, and a very few Small Skipper and Common Blues.

In addition, but not photographed, were Small and Green-veined Whites, single Red Admiral, Brown Argus, Small Heath and a Purple Hairstreak that had a lucky escape from a spider’s web up in an oak canopy.  And flying around the fields there were Emperor, Brown Hawker and Common Darter dragonflies, and Willow Emerald and Common Blue Damselflies.

Aside from insects, there was plenty more of interest, including a spider Enoplognatha with its hoverfly prey, abundant Oak Mildew, artichoke and marble galls on Oaks, and a good fruiting of sloes.

And just to finish off, the things we didn’t see as a group, but which I found on my recce a couple of days previously: leaf mines on oak and galls on Wild Rose (we just didn’t have time to hunt them all out on the walk)…

… Box Bug and Cinnabar caterpillars

… Ringlet and Small Copper

… and a hoverfly Xanthogramma pedissequum, known aptly as the Superb Dayglower.

Yes, Lower Lodge performed very well as always, a powerhouse of biodiversity on our doorstep!

The Wild Side of Beth Chatto Gardens: June 2026 – deluge and furnace…

June was a month of two halves. After the record-breaking May heatwave broke down at the very end of the month, the first two weeks of June were damp, with some very heavy rain, before the even more record-breaking heatwave reasserted itself. Is anybody listening to the cries of the Earth?

My visits to the garden were all in the latter half and included a moth event covered in this blog Midsummer Moths 2026 at Beth Chatto Gardens | Chris Gibson Wildlife, successful up to a point but I think showed signs of the impact of the vagaries of the weather.

Bird broods were very much in evidence, including Great and Blue Tits, Blackcaps and Blackbirds. Three singing male Whitethroats and four Goldcrests were presumably proclaiming territories for their second broods, and my personal first record of a Coal Tit in the garden was also of a singing bird, perhaps a second-brooder that may have first bred elsewhere. Grey Herons seem to be dispersing from their heronries, with several flying over and one at rest by the Reservoir for some hours, while Swallows and a Kestrel were feeding over the long grass of the overflow carpark.

In the garden through the heat, insect activity during the hottest part of the sunny days was much reduced, but by seeking out the cooler times and shady spots, it was possible to find plenty of interest. But not always to photograph it: Silver-washed Fritillary, Rose Chafer and Willow Emerald damselflies were all zipping around, refusing to settle. And always active were the Hummingbird Hawkmoths that occasionally showed especially in the Reservoir Garden:

Painted Ladies have been present throughout the month, those at the end especially being pristine and presumably the offspring of previous immigrants. And the summer butterflies are starting, with Large and Essex Skipper (the latter the first confirmed record for the garden) and Purple Hairstreaks occasionally descending from the Oak canopies, while Speckled Woods loitered in the sunflecks.

Dragonflies and damselflies have continued to perform well, especially around the ponds, including a coordinated emergence of Common Blue Damselflies that proved a bounty for the Cucumber Spiders. But most exciting were the Banded Demoiselles: after a few years when they have appeared with us sporadically and unpredictably, this month finally they seem to have consolidated. Let’s hope they stay!

Of course there was plenty more to see as well, including Yellow-and-black Longhorn, Lily Beetles and masses of pollen beetles…

… mating Fencepost Flies, nectaring Tachina rufa agg. parasite-flies and sunning Dock Bugs …

… plus lots of lovely Hymenoptera: Iris Sawfly larvae, Gwynne’s Mining-bees in the Campanula flowers, Sphecodes blood bees that feast on nectar but whose larvae parasitise mining-bee nests …

… and around the bee hotel, Large-headed Resin-bees and a ruby-tailed wasp Chrysis ignita agg., the latter another parasite but on certain solitary wasps.

And as always a goodly array of new finds for our garden list, as well as those already mentioned, including a couple of moths, Epagoge grotiana and Virgin Bagworm…

… lots of Hollyhock Weevils, a fairly new arrival in the country that appeared for us in Wivenhoe three years ago …

… two ants, Myrmica rubra and Temnothorax nylanderi …

… a parasitic javelin wasp Gasteruption sp., being buzzed by Yellow-faced Bees …

… and Wool Carder-bee nesting in our bee-post.

So it was quite a challenging month because of the weather. Maybe July will settle down, and if anyone wants to join me, my Wildside Walks on 17th July and our Moth Morning on 18th July are all open for booking on the website Courses & Workshops – Beth Chatto’s Plants & Gardens.

Wivenhoe in Bloom – through the eyes of an eight-year-old

When the muse takes her, Eleanor, now 8, likes nothing more than exploring and capturing the world around her through a cameraphone.

Last weekend was one of those lovely occasions, an hour together in the sun, with no guidance, no restrictions, just free to photograph whatever struck her.

Mostly she gravitates towards flowers, although not exclusively., especially when insects present themselves…

Whereas I would deliberately try and avoid the tangible evidence of human beings in my own photos, Eleanor seemingly relishes those juxtapositions.

And I would of course always seek pristine perfection, but her photos demonstrate so clearly there is beauty in senescence! That certainly makes me look anew!

Then there is the positioning of the subject. OK this might be random, but seeing the sequences of her pictures where she starts with it centred and then increasingly shifts the focus to one side or another makes me think her artistic appreciation is somehow innate. The number of images where the subject bleeds off the edge without compromising the beauty of the whole has to be deliberate?

Likewise throwing focus: indeed she patiently explained to me how she gets the shots where focused background detail is highlighted by a blurry foreground…

…as well as getting so close into the subject, it is driven to abstraction (my words!).

And finally, by being younger, smaller and more supple she manipulates perspectives in ways I could now only dream of!

The apogee of this (so far) for me is in the picture of a small tree from ground level, looking like a foliar firework exploding into the heavens.

I know I am biased but I am a very #ProudPapa!

Midsummer Moths 2026 at Beth Chatto Gardens

Our June moth event in Beth Chatto Gardens took place as normal just before the equinox. On the face of it the night was perfect: calm, humid and very warm, with temperatures not falling below 20ºC. But such are the uncertainties (and joys!) of moth trapping, reflecting not only weather on the night, but also recent weather extremes (eg the May drought and more recent downpours) as well as seasonal trends, that in fact we were a little disappointed. Or thought we were until we totted up the total and found we had recorded four more species than on the equivalent date in 2025, last year being the record-breaker to date. For a full listing over the years, see here BC MOTHS TOTALS.

71 macromoth species and 33 micros is certainly a good haul, but the slight disappointment was at the number and especially diversity of the big, bright ones, the crowd-pleasers. And again, we cannot really complain at the twenty or so Elephant Hawk-moths, a couple of Small Elephants, six Buff Tips, Swallowtail Moth, Ghost Swift and a lovely Puss Moth, mostly compliant and happy to be passed gently around the early morning crowd. The Ghost Swift even laid eggs as we watched, scattering them freely where it was resting, rather than as with most species attaching them firmly to their substrate.

Among the smaller macromoths were colourful ones such as Brimstone Moth and Rosy Footman…

… whitish ones, like Yellow-tail, Brown-tail, White Satin (playing dead!), Miller and Dwarf Cream Wave…

… distinctively speckled and barred ones: Latticed Heath, Willow Beauty and Peppered Moth …

… and a whole host in every shade of brown: Lackey, Fen Wainscot, Dotted Fanfoot, Clay, Cypress Carpet, Uncertain, Dingy Shears, Bright-line Brown-eye and Minor Shoulder-knot, a litany of names almost as euphonious as the Shipping Forecast!

Some of the brown ones are also distinctive by having shaped wings like Beautiful Hooktip or a characteristic resting posture, like the Festoon, the latter a nationally scarce species of old oak trees in the south-east of the country.

Micromoths seemed to constitute a higher proportion of the catch than in previous years. But not all micros are small and some are rather beautiful, and certainly should not be overlooked, even though they often don’t have widely used English names. Here are some of the more colourful ones: Carcina quercana, Agapeta hamana, Lozotaeniodes formosana and Mint Moth…

… and equally striking monochrome morsels: Bird-cherry Ermine, Ethmia quadrillella, Diamond-back, Platytes alpinella, Zeiraphera isertana and Homoeosoma sinuella.

And always interesting is the bycatch of other insects attracted to the light, including pond-dwellers (in their pre-adult stages) such as the mayfly Cloeon dipterum and the caddisfly Stenophylax permistus

… a green lacewing Chrysopa carnea and Birch Shieldbug…

… a couple of plant-bugs Stenotus binotatus and Phytocoris dimidiatus.

And when all was counted up at the end, we found in the trap some 35 new insects for the garden list: moths, bugs, caddisflies, a mayfly and best of all a Brown Chafer Serica brunnea, with only about four previously recorded sites in north Essex.

Moth-trapping (and release unharmed) provides a window into the night life of the garden, as well as giving the privileged opportunity for attendees to experience the delight of the early morning calm before floods of garden visitors arrive. So if anyone fancies it, our second event is planned for 18 July, booking via the Beth Chatto website at Marvellous Moth Morning – Beth Chatto’s Plants & Gardens

The Wild Side of Beth Chatto Gardens: late-May delights

The photo above, a myriad of fairies photobombing a Monet masterpiece, encapsulates the joy of late May in the gardens. Everything is getting on with what they need to do, feeding or breeding or dispersing, furiously because they know the retreat of the sun is only a month away.

The 26th saw peak damselflies mating (mostly Azure, Large Red and Blue-tailed) alongside the first emerging Common Blue Damselflies and Banded Demoiselles AND the mass emergence of dragonflies (mostly Four-spotted Chasers, with a few Broad-bodied and Scarce Chasers, Common Darters, Emperors and a Southern Hawker. Fittingly, and thrillingly, this coincided with my Bug Safaris, a privilege to share it with kids (of all ages!). This was the week our ponds disgorged, a couple of weeks after many garden ponds whose water volume is much lower, so the water warms more quickly, speeding up development.

And the rate of change is just so fast. On a daily basis. A day later, damsels had peaked, dragons were still coming, but the garden was inundated with Painted Ladies, most very fresh-looking so perhaps offspring of the influx a month ago. And the trees and bushes were full of tweeting baby Blue and Great Tits, and Blackcaps: a squeakscape where a day before there was a songscape.

Apart from the Painted Ladies, butterfly action had scaled back from early May: the ‘June gap’ arrived early. But to tide us over were Orange Tips on the Dame’s Violet and onions and Green Hairstreaks on the Thyme, along with a good emergence of Common Blues.

It was a warm two weeks, at times extremely hot, sunny and dry: record-breaking, albeit not-in-a-good way. But generally the insect life seemed to enjoy it: some other highlights included Mint Moth, Cinnabar, Yellow-tail caterpillar and the larval shrouds of Spindle Ermine…

… Thick-thighed Beetle, a soldier beetle Cantharis livida, Adonis’ Ladybird and Two-spotted Malachite Beetles, including this pair in a prolonged bout of ‘kissing’, the male feeding her pheromone-laced food to try and woo her…

… Hairy Shieldbugs and Orange-tailed Mining-bee …

… and a good selection of flies including the lovely hoverfly Xanthogramma pedissequum, and a couple of parasite-flies Tachina fera and Tachina lurida.

I enjoyed myself too, taking time out to grow the garden wildlife list. Every visit produced something new, in some cases rare or absent (probably underrecorded!) in Essex but equally some very widespread that we just haven’t noted here before. Two new mite galls are a case in point: the Lime Nail Gall is found on almost every Lime tree, whereas the Silver Maple Bladder Gall is a recent arrival in this country and still spreading:

There were new flies to the list: the parasite-flies Phasia barbifrons and Blepharipa pratensis, and the robberfly Choerades marginata

… new beetles: the thistle weevil Rhinocyllus conicus and Mallow Flea-beetle Podagrica fuscicornis

… and new wasps: the parasitic Ichneumon xanthorius, a digger wasp Cerceris quadricincta (a strongly south-eastern species, rare in the UK) and a beautiful ruby-tailed wasp Chrysis ignita agg.

The list is growing every month, and but we hope to have a working draft available in the autumn!

And so we are fast into summer. Maybe time to relax a little as things settle in. Or maybe not: all it takes is a few days of deep south winds, and as we have seen repeatedly the Beth Chatto Gardens rarely fail to produce surprises!

The Wild Side of Beth Chatto Gardens: all change on the insect front!

Insect populations are ever-changing and those changes an endless source of fascination. In the first two weeks of May I have been to the gardens leading walks on two days and a further visit to try and reconfirm something I had seen on the previous occasion. And in that time the suite of insects has changed hugely, spring being ushered in by the advent of summer, even given the sometimes indifferent weather.

But there have been other changes too. We have seen several new arrivals to the garden, including sawflies, flies and beetles. Sawflies are actually wasps, ones that lack the wasp waist between thorax and abdomen, and have caterpillars rather like those of moths, rather than the grubs associated with most wasps. This seems to have been a Sawfly Spring, as I’ve seen more this year than ever before. There have been the regulars, Solomon’s Seal and Iris Sawflies all over their respective foodplants, and in a month or two the plants will be bearing the signs of larval chomping. Another species Selandria serva feeds on grasses, sedges and rushes, and has also been prominent around the garden – we have found it in the garden only a couple of times prior to this month. The National Biodiversity Network maps show only a couple of spots for this in Essex, but this is perhaps more down to the fact the sawflies are not a widely recorded group: spots on maps may represent more the distribution of competent observers rather than the beastie itself. All the comment below must bear that caveat!

A couple of new garden records are of Macrophya species. M. albicincta is an Elder-feeder but doesn’t seem to have been recorded from Essex. And M. teutona seems even scarcer: it was first found in the UK last year near to Bury St Edmunds and the map shows just one other location close to the first. So ours might just be the third British record…and we would be a great place for it as its larvae feed on spurges.

And more sawflies apparently new to Essex! Resting on a Foxglove leaf was the distinctive larva of Periclista pubescens, an oak-feeder and so had probably dropped from the tree above. And then were the lovely little black-headed sprites flittering around the bases of our ferns, Ostrich Fern especially. Evanescent creatures that almost disappeared as they were observed, they were Stromboceros delicatulus, the larvae of which feed on ferns and so not surprisingly recorded mostly in the damper corners of our nation.

But new insects for the garden were not all sawflies. The cloudy-winged non-biting midge Psectrotanypus varius and soldier beetle Rhagonycha lignosa are both only sparsely scattered in Essex, most localities being in the west of the county.

But for me the most exciting newbie was another beetle, a spotty chafer Oxythyrea funesta that is an old friend from my travels in Mediterranean regions. It has cropped up sporadically in the UK, probably mostly from accidental imports with plants, but over the last decade seems to have become pretty well established, especially in London and round Portsmouth. There are probably a couple of other Essex records, at least one of which in a garden centre is likely to be an accidental import. No such likelihood with ours though, given that all our stock is home-grown.

It was wonderful to watch it (or just possibly two of them) chomping the poppy and Galactites stamens in the hottest part of the garden, against the south wall of Beth’s house. The image of one sitting in Galactites will linger long in my memory, an instant transportation to one of the places I love most, Menorca. And if I am not travelling to such places so much any more, conscious of our granddaughter’s future in an already overheated world, I can console myself with the thought that I don’t need to: the Mediterranean fauna is coming to me! That impression was solidified yesterday when the soil below the chafer started to crawl with little orange morsels, first instar nymphs of the Firebug. Another constant companion in southern Europe, these have become established in Britain only within the past decade, including many places in northeast Essex. But hitherto, until the staff started seeing the adults a month ago, not in Beth Chatto Gardens: well, they are here now – and breeding!

What of other sightings? Well, the butterflies seem to have hit their ‘June gap’ early. Most overwinterers and spring specialists have gone, but the summer emergers are starting, with both Common Blue and Brown Argus. And one of my groups was entranced by half-a-dozen Green Hairstreaks nectaring on a bed of Thyme, and resting much less obtrusively on surrounding vegetation.

There was been a reasonably large emergence of Green Longhorn moths, dancing around when the weather was warm and still enough. And there seem to be Brown-tail Moths everywhere, thankfully not it seems in rampaging, defoliating hordes, but in some cases experimenting with food choice, such as Large Lord’s-and-Ladies.

As summer approached so we are expecting the songs of grasshoppers and bush-crickets to fill our quit moment. And here they come, a first instar Speckled Bush-cricket is out of the starting blocks…

It is this time too when the ponds start to disgorge their delights around the gardens. No dragonflies yet (our ponds are large and take longer to warm up than garden ponds), but Alderflies are everywhere, along with three species of damselfly: Azure, Large Red and Blue-tailed (in two colour forms).

 

Bees have done well, with Red-tailed and Early Bumblebees more numerous than in recent years, and lots of foraging Red Mason-bees taking advantage of our floral offerings.

And other lovely things to see included flies, the Narcissus Bulb Fly, the cranefly Ptychoptera contaminata and a couple of parasite-flies, Thelaira nigripes and Tachina fera.

Beetles included lots of click-beetles, mostly Athous haemorrhoidalis, the shining-green weevil Polydrusus formosus and a whole herd of stag-beetle larvae the garden team found (and saved!) under a rotten tree trunk slice. Most probably these are Lesser, not the rarer Greater Stags, but we can hope!

And finally a few bugs have been out and about, here Rhabdomiris striatellus, Harpocera thoracica and Hairy Shield-bug.

So a month of many delights, and the good news is there is another half of it to go! If you fancy looking at insects in Essex, there is really nowhere more exciting than Beth Chatto Gardens. You might even fancy joining one of my walks or moth events as advertised on Courses & Workshops – Beth Chatto’s Plants & Gardens? And if you turn up and it’s too cold or wet for insects, there are always the fantastic flowers…

… including my absolute favourite, the gorgeous Bogbean. How can you resist?

The Wild Side of Beth Chatto Gardens: Spring in full flight

April saw me heading to the gardens on three occasions in mid-month, twice to lead walks (two for the National Garden Scheme and the first two of my summer monthly WildSide walks) and one just me and my camera, a moment of peace in a mad world.

Five walks on three days in just a little over a week might seem like overkill, but this time of year it really isn’t. In the full flight of spring, nature can change perceptibly every few days. And this year was no exception, especially as the lack of rain for about five weeks and rising temperatures completely changed track from the past wet winter, and pushed us into incipient drought. These mood swings of nature, actually more like handbrake turns on a sixpence, are what we must expect and live with in the climatically weirded future. And so must our garden plants and wildlife. Some will not be able to, so my advice as always is get out there now and appreciate just what riches we have!

The speed of change was almost frightening. Take that wonderful yellow peony Paeonia mlokosewitschii (aka Molly the Witch), in tight bud on my first visit, full flower six days later and three days futher on, starting to fade. A plant of highly transient glory, but a favourite of the garden bees!

Many other flowers of course, a plethora of potential food sources for insects and a delight to photograph:

And not to be outdone, the unfurling fern fronds and red maple foliage added their own highlights to the masterpiece of spring:

Butterflies have yet to emerge in real force, especially since the overwinterers have started to fade. But the whites are putting on a strong show, with Small, Green-veined and Orange Tip by the first visit, Large White joining them by the final date, along with the first Green Hairstreak and Speckled Wood.

The first visit also coincided with the first emergence of the year of Large Red Damselflies, always the earliest of its group to appear, along with other aquatic insects like Alder-flies, and remarkable numbers of adult Iris Sawflies, on and around the emergent iris leaves and whose larvae will be responsible for nibbled edges to leaves this summer.

Back on dry land, there were plenty of the usual bumblebees, including rather more Red-tailed than we have come to expect in recent years:

Hairy-footed Flower-bees were still patrolling the borders of comfrey and lungwort, not only for food but also for each other, with many interactions between amorous males and seemingly uninterested females noted! Other solitary bees included Yellow-legged and Chocolate Mining-bees, one of the furrow-bees, and Flavous Nomad-bee. The several species of nomad-bee seem to be in remarkable numbers this spring compared with previous years…

Two others from the same insect group, Hymenoptera, were queen Common Wasps, feeding and rasping wood to build their nests with, and the currant galls of the spring generation of the Spangle Gall Wasp on Oak catkins:

Moving to flies, some of the most numerous were the Bibio species. first B. lanigerus and B. anglicus, with the first true St Mark’s Fly B. marci on the first visit. 14th April is early for this species, named because it emerges on or around St Mark’s Day, 25th April. During the second visit, they were very numerous, and by the third, almost gone – perhaps down the throats of birds, as they are favourites of Swallows.

Hoverflies increased greatly through the month, and included many flower-flies Syrphus sp., together with Batman and Footballer Hoverflies , and lots of Epistrophe eligans.

Other easily recognised flies were Yellow Dung-flies, the dance-fly Empis tessellata and the parasite-fly Tachina fera

… along with many other less distinctive, but still important , parts of our garden’s biodiversity.

Ladybirds are still more abundant than I have ever seen before at this time of year, the offspring no doubt of those that arrived en masse last July. And while most are 7-spots, a selection of other species such as 14-spot Ladybird is starting to emerge.

Bugs included the first Harpocera thoracica of the year, with plenty of Hairy and Green Shield-bugs, and also a lovely find of a mating pair of Gorse Shield-bugs, a rather uncommon creature in the garden.

On the reservoir, Dabchicks were singing and a pair of Tufted Ducks has seemingly settled in. All around the garden, birds are in song, residents like Greenfinch, Robin, Goldcrest and Song Thrush, alongsideside the summer visitors, especially Chiffchaff and Blackcap.

On the first two visits a Cetti’s Warbler was singing on the edge of the garden, only the third record for the site, but on the third visit its apparent territory had been filled by a singing Whitethroat, again not common in the garden. And overhead plenty of action too, from feeding Swallows to displaying Buzzards, flyover Egyptian Geese and Red Kites, along with Mediterranean Gulls and a Lesser Black-backed Gull, both rarely appearing in our sights.

Another fantastic month in the Beth Chatto Gardens, the incidental nature reserve!
