The Wild Side of Beth Chatto Gardens: after the rain……..

Heavy drizzle preceded the fourth in my series of  ‘Meet the Wandering Naturalist’ sessions in the Gardens, and although it stopped ten minutes before the start, the first walk was still a pretty sodden affair. Not that it prevented several interested visitors joining me strolling around and looking at nature…

… and realising how lucky we were, given the ring of lowering clouds all round!

Flying insects were relatively few and far-between, most sitting around forlornly, only the bumble- and carder-bees, safely wrapped in their fur coats, creating a buzz in the borders, with Nepeta, Hylotelephium, Salvia yangii, Caryopteris and Vitex agnus-castus being especially sought out.

With a hungry nest to provision, Hornets were busy flying around and entering their nest in a hollow Cherry tree, although the nest entrance was tantalisingly out of sight; however the occupants of one of the above-ground-nesting wasp species (perhaps Median Wasp) remained quiescent.

And even if the insects were few, there were always the rampant scentscapes to enjoy, as always after rain, along with the twittering of House Martins and Swallows migrating overhead and the plaintive autumn song of Robins starting to swell, and of course the displays of rain-drops on many a plant, especially the mercurial spattering on Alchemilla:

During the second hour though the weather changed markedly. The sun came out and turned the garden into a sweltering, humid cauldron, with butterflies (seven species) and dragonflies (three species) responding immediately:

Echinacea, Rudbeckia, Eupatorium, Scabiosa and Foeniculum quickly became the focus for foragers, bees and hoverflies especially, but also a whole lot more …

… and of course for predators keen on making a meal of the pollinators …

… as well as other lookers-on:

Summer may be ending but the garden goes on; there are still plenty of flowers still to peak, to brighten up our lives and deliver their sustenance to the natural world:

If anyone would like to join me in the garden looking at its wildlife, I am planning on repeating this walk (weather permitting) on both 15th and 29th September, between 1100 and 1300. No need to book, just come to the garden (normal entry price – see our website for details) and ask at the Visitor Information Centre where I will be and when, and come along and find me! Nearer the time, if the weather is looking at all dodgy, please feel to contact me using the Contact tab above to check it is likely to be running.

While one can never predict what nature will deliver, I imagine it will be the copious nectar and pollen sources of members of the daisy family Asteraceae, together with Hylotelephium ice-plants in the gravel areas and flowering Ivy in the hedges that will be sustaining insect life. Birds could be heading south overhead and maybe the first fungi of autumn will be sprouting. So much to look forward to!

The Wild Side of Beth Chatto Gardens: the slide into Autumn…

What a difference a couple of weeks makes! Compared with my previous walk The Wild Side of Beth Chatto Gardens: the steamy jungles of Essex!! | Chris Gibson Wildlife, the third in my series of  ‘Meet the Wandering Naturalist’ sessions in the Gardens coincided with a rather dull, blustery day; that and the advancing season combined to reduce the insect activity substantially. Nevertheless, there was more than enough for all who joined me strolling around and looking at nature.

Butterflies in particular were well down from their superabundance of the past month, with just a few Small Whites, Holly Blues, Gatekeepers and Red Admirals on show.

And the available insect food sources have moved on with the season.  Buddleia, Lavandula and Eryngium are all but over (though where any flowers remain they are still exerting strong attraction) ……

… Bistorta, Nepeta and Origanum are perhaps starting to fade but a major draw nonetheless ….

… and now the daisy family is really beginning to assert itself as a force in the garden. Echinacea in particular is a magnet for bees, hoverflies and many more.

Of course we are lucky to have the space and different ground conditions to grow plants that provide sequential nectar and pollen resources through the year, and at the moment there is a whole host of others sharing the  role:

Honeybees, bumblebees and hoverflies are among the most numerous of insect visitors …

… while parasitic tachinid flies also seem to be especially abundant at the moment. While often overlooked, their role in parasitising lepidopteran and other larvae cannot be overstated. The more the garden supports predators and parasites, the more its insect abundance (what some may call ‘pests’) are kept in check without recourse to poisons. Let’s hear it for our army of tachinids, ladybirds and wasps!

Dragonflies, damselflies and bush-crickets are also part of this predator realm, albeit relatively minor players numerically. This normally camouflaged Speckled Bush-cricket showed up remarkably well on the vivid Lythrum flowers …

… and damselflies included both the typical late-season Willow Emerald and this beautiful lilac-fronted form of Blue-tailed Damselfly, echoing the colours of its chosen perch.

But the bonus from their being fewer insects on show was that there was more time to talk about other wildlife, plants in particular. Coming into late summer, many are in fruit, and none is more distinctive than the unique churro-like seeds of Meadowsweet:

And although it may be a stretch too far to call planted plants ‘wildlife’, certainly anything that has embraced its wild side by spreading itself around the garden deserves that name. In the Gravel Garden, Fox-and-Cubs is doing that in such an artistic way that surely Beth would have approved…

… while in the same area, Sickle-leaved Hare’s-ear weaves its filigree fronds as a golden thread, linking the beds thematically and also through the years: once native to Essex, and only to Essex, when its habitat was threatened by roadworks half century ago it was rescued by a band of botanists – and it is likely that some of the seed came into Beth’s hands, and garden.

If anyone would like to join me in the garden looking at its wildlife, I am planning on repeating this walk (weather permitting) on 1st September, between 1100 and 1300. No need to book, just come to the garden (normal entry price – see our website for details) and ask at the Visitor Information Centre where I will be and when, and come along and find me! Nearer the time, if the weather is looking at all dodgy, please feel to contact me using the Contact tab above to check it is likely to be running.

While one can never predict what nature will deliver, my guess is that with the end of the season firmly in sight, it will be the copious nectar and pollen sources of members of the Asteraceae and also just-now-opening ice-plants of the genus Hylotelephium (perhaps better known as Sedum) that will be sustaining late breeding attempts and provisioning others for hibernation.

#WildEssexWalks – an evening with trees and bats in Wivenhoe Park

Towards the end of a sunny summer day, #WildEssex headed for Wivenhoe Park, home of the University of Essex. Landscaped around Wivenhoe House in the mid-18th century, the park boasts lakes and grassland, some now commendably being allowed to bloom through the season, providing for both flowers (like Common Knapweed) and insects, here the galls in thistles formed by the picture-winged fly Urophora cardui ….

…. but most importantly, a collection of magnificent trees from all over the world. The oldest, native Pedunculate Oaks, certainly pre-date the hall, and provide habitat for all sorts of wildlife, including cracks and crevices for roosting bats, as we saw at the end of the walk.

This summer all the oaks are afflicted by Knopper Galls, taking the place of the acorns, in densities greater than we have ever seen before. The Jays may go hungry this autumn, although the also very abundant beechmast may help compensate.

Other exotics included Red Oaks, Mulberry and Walnut, the latter with the most wonderful sweet smell when its leaves are scrunched. So too with the many conifers, Coast Redwood with the most invigorating resinous aroma, mixing bitter oranges with parsley. Much more alluring than the other two of the redwoods of the world, Giant and Dawn Redwoods, also featuring in the park, or the north African Atlas Cedar and mid-USA Swamp Cypress: all have distinctive scent but none as memorable as Coast Redwood.

A  Cedar-of-Lebanon, de-rigueur for every aristocratic house in centuries past droops gracefully outside the main entrance, and in the same area there are groves of the more prosaic Horse-chestnut (aka Conker Tree). These two species do however share one feature: they are nowadays very rare, endangered even, in their aboriginal habitats, the mountains of the Middle East and Cyprus, and the Caucasus respectively. Thank goodness for parks, gardens and arboreta, Arks to help species from seriously troubled parts of the world survive into the future.

As the sun set around a quarter past eight,  twilight soon descended and we set up camp by the lower lake to await the emergence of bats. It started slowly but within an hour, just before it was fully dark, we were among them in abundance, between the trees, overhead and over the water. With the bat detectors we recorded mainly Soprano Pipistrelles, but also Common Pipistrelles and Daubenton’s Bats joining the feeding frenzy, a wonderful end to a lovely walk.

That’s it now for #WildEssex in August. Our next planned trips are to Wrabness Nature Reserve 4 September (also an evening trip) and Brightlingsea on 18 September, our annual charity event, this time supporting the wonderful work of Springmead Garden.

The Wild Side of Beth Chatto Gardens: the steamy jungles of Essex!!

Yesterday it was the second of my ‘Meet the Wandering Naturalist’ sessions in the Gardens – strolling around and looking at wildlife (insects in particular) for a couple of hours and showing it to any interested visitors.

Insect abundance was not quite as great as the first, two weeks ago, and many of the butterflies were distinctly worse for wear after the downpours of the past week, but there was more than enough to fill our time, helped by the sultry, warm, humid, still weather, more jungle than Essex summer. Much better weather in fact than the forecast for thundery showers – the sun was patchy, but very warm when out, a thunderclap mid-morning preceded a very light shower until five minutes after the session finished when the heavens opened with what was probably the spikiest rainstorm of an already wet summer.

The star performers plant-wise were Bistorta and Lavandula, especially for wasps/hoverflies and bees respectively, and Origanum for the whole spectrum of insects. And the favourites from last time, Eryngium and Buddleia, although fading fast still have serious pulling power…

But of course these plants were only a small selection of the resources on offer to our insects, as the photos below show:

Showiest of all the insects of course were the butterflies, with 14 species logged, including a major emergence of second-brood Holly Blues, although the very best, a stately Silver-washed Fritillary didn’t hang around for a photo!

Hoverflies too were everywhere, and included two of our largest species Volucella zonaria (Hornet Hoverfly) and Volucella inanis, among numerous other species…

… along with other flies from a whole range of families:

Honeybees, bumblebees and wasps, including the locally scarce Median Wasp on Ruta, as seems to be usual, added to the pollinating hordes…

… along with less celebrated but no less important pollinators such as beetles.

Of course not all insects are subsisting solely on nectar and pollen: in our garden jungle there are also predators. Below is Kite-tailed Robber-fly with a Marmalade Hoverfly dinner and a Bee-wolf wolfing a bee!

When flowers are on offer, it is always too easy to overlook other wildiife action around the garden, or perhaps more aptly ‘inaction’, sitting around on the foliage basking, looking for food, or nesting…

So, another wonderful two hours immersed in the Wild Side of Beth Chatto Gardens …

If anyone would like to join me in the garden looking at its wildlife, I am planning on repeating this (weather permitting) on 18th August and 1st September, between 1100 and 1300 each day. No need to book, just come to the garden (normal entry price – see our website for details) and ask at the Visitor Information Centre where I will be and when, and come along and find me!

While one can never predict what nature will deliver, my guess is that, as we slide gently towards autumn, it will be members of the daisy family such as Echinacea and Eupatorium that we will be celebrating next time!

The Wild Side of Beth Chatto Gardens: a butterfly bonanza!

Last week, I held the first of my ‘Meet the Wandering Naturalist’ sessions in the Gardens – strolling around in the sun, looking at wildlife for a couple of hours and showing it to any interested visitors. An awful job, but someone has to do it! And the discussions and questions covered a whole series of topics from choosing the right plants to attract butterflies and how to identify the insects in the garden, right down to the practicalities of managing Phormium.

And quite fortuitously, this session coincided with what was the best day for butterflies and other insects I have ever experienced in the garden in 30 or more years of visiting it. At least 15 species of butterfly, some in their hundreds, plus a whole raft of others, from moths to bees, flies and dragonflies made for a very entertaining and engaging morning.

Insects were everywhere, but as always there were a number of stand-out plant performers., one being the Butterfly-bush Buddleia davidii, especially the one in the Scree Garden, next to the fast-fading Buddleia crispa on the house wall, a star performer earlier in the month.

At one time I estimated a couple of hundred individual butterflies of eight species around this one bush: it was almost like a window back into my youth, that almost-forgotten time when in my mind’s eye every Buddleia was covered in butterflies all summer long.

Especially in the Gravel Garden, plants in the mint family Lamiaceae were those drawing in the pollinators. A carpet of Teucrium x lucidrys was literally humming with bumblebees, perhaps 20 in a couple of square metres, many deep within the foliage, giving themselves away by vibrating the shoots….

Together with Origanum, Thymus, Betonica and Lavandula, this family fills the garden with life, sound, movement and scent, with Brown Argus butterflies and Mint Moths in addition to the more numerous species.

In the damper areas of the Water Garden, it was the genus Bistorta doing the heavy lifting, with social wasps and Honeybees in vast numbers:

And so to the Reservoir Garden and the star performers to beat them all, Eryngium. At their very peak, the sea-hollies (especially Eryngium planum ‘Blaukappe’) were covered in an array of bees, wasps (including dramatic Bee-wolves), beetles, butterflies and lacewings, greenbottles, tachinid flies and hoverflies, including the very largest, the Hornet Hoverfly.

Particularly in the latter part of the summer, it is members of the daisy family Asteraceae that will take over lead responsibility for feeding the flocks, and all through the gardens this is starting to happen, including Hummingbird Hawk-moths on Cirsium.

Aside from all the plants mentioned above, so numerous were the insects that they were visiting the whole range of available flowers. A Brimstone enjoyed Dianthus, and Small Whites were frisking and frolicking wantonly on the Verbena

Deep in the day-lilies, hoverflies were browsing on pollen. Although we usually think of flies supping nectar, they do need a pollen meal to get the nutrients needed for sexual maturation, and of course this contact with pollen is what makes them as valuable as bees for pollination.

And then on the Ruta flowers, and only those specific flowers so far as we could see, several examples of a large, unfamiliar wasp. These were Median Wasps, first found in Britain in 1980 and spreading, albeit still uncommon in Essex.

Of course, flowers are not everything, and there were invertebrates everywhere, including several Willow Emerald damselflies and an impressive Labyrinth Spider.

Readers of these blogs may remember one from 2020 Murder at the Garden Pond: Thalia dealbata – the (not very) beautiful assassin | Chris Gibson Wildlife. This detailed the antisocial, pollinator-killing habits of Thalia dealbata, and led to my increasing involvement with the Beth Chatto Gardens. One of the talking points during my garden session was this, as the ‘killing fields’ had just been initiated as the flowers opened. However, very much to their credit, the staff were straight in there removing the flower-stalks, to save the insects from a lingering death while allowing the stately beauty

If anyone would like to join me in the garden looking at its wildlife, I am planning on repeating this (weather permitting) on 4th August, 18th August and 1st September, between 1100 and 1300 each day. No need to book, just come to the garden (normal entry price – see our website for details) and ask at the Visitor Information Centre where I will be and when, and come along and find me!

Marvellous moths morning at Beth Chatto Gardens – late July

Our second ‘Moth Morning’ of the year at Beth Chatto’s was a great success! The first one (see here) a few weeks ago had turned out to be rather disappointing moth-number-wise, so we were doubly delighted by the number of winged beauties that graced our trap this time.

We set the trap on a reasonably warm night, and luckily Chris’ Heath Robinson waterproof cover was assembled ‘just in case’. Although the BBC forecast 0% chance of rain, we had a huge shower late evening, which would have proved fatal for an unprotected hot bulb! The following morning we arrived to find the trap cover and surrounding sheets dotted with moths of all shapes and sizes and a quick peek in the trap itself was very encouraging.

Our group who had signed up for the morning event were pleased and interested to see the moths as they were unveiled from the trap one by one. See here Beth Chattos moth morning 22 July 2023 for the full list of species; clear highlights were Elephant Hawk-moth, several Rosy Footmen and a Ruby Tiger, all in their red and pink shades:

Naturally there were plenty of ‘standard’ brown moths like this Dun-bar, but even some of those were remarkably colourful. We have never seen such a richly marked Broad-bordered Yellow Underwing before…

Yellow-brown shades came from Scalloped Oak and Buff Ermine…

… while largely white ones included Least Carpet, Clouded Border and Brown-tail.

We didn’t concentrate too much on micros, although there were several Ringed and Small China-marks (reflecting the proximity of the ponds) and three species of small ermine (Willow, Spindle and Apple Ermine).

And finally from the trap, two views of a pristine Pebble Prominent, one to show its namesake prominent scales in profile and the second to show its remarkable camouflage against a woody backdrop.

In the event a total of some 40 species of macromoths plus a dozen or so micros were logged, and released unharmed. To these we must add the ‘bycatch’ of  green lacewings, caddisflies and a tiny, rather attractive non-biting midge Microtendipes pedellus. Why remark on this? Well, it seems to be very scarce in Essex indeed, the Essex Field Club distirbution map showing only two previous locations, neither of which is anywhere near us!

One bonus of these Moth Mornings is that our group has exclusive access to the garden between 9 and 10am. We had hoped for a sun-dappled, warm morning – the reality was dull, overcast and unseasonably chilly – but at least no rain (unlike later in the day!)…

We spent a very enjoyable hour walking around the garden, looking at plants that were attracting insects even at that early hour and in somewhat adverse conditions.

There were bumblebees, Honeybees and social wasps  galore, especially among the Bistortas, and a range of hoverflies, including the largest of all (if rather fleetingly) the Hornet Hoverfly. Pond-life was represented by Willow Emerald and Blue-tailed Damselflies:

Our personal favourites the true bugs were represented by some ‘teenage’ Green Shield-bugs and a Tarnished Plant-bug, and the galls by some emerging knoppers on developing acorns:

… while the few early butterflies included Red Admirals and Gatekeepers, and a confiding Brown Argus.

And to complement the moth trap, we found some ‘free-range’ moths, including Latticed Heath on the Eryngium,  the case of a tiny base-bearer Coleophora sp., one of the ‘bird-poo micros’  White-backed Marble, and best of all the Scarce Forest Tubic, an uncommon moth in Essex and the country as a whole, typically an inhabitant of ancient woodlands.

If you are interested in such events, please keep an eye on the Beth Chatto website for similar events next spring and summer. Provisional dates are 22nd June 2024 and 20th July 2024. These are run by and in support of the Beth Chatto Education Trust, established by Beth to carry forward her passion for plants and the ecological approach to all.

#WildEssexWalks – High Summer in Wivenhoe’s Lower Lodge

Good news! The worries of the past few months have been partially dispelled. Our traditional midsummer Lower Lodge walk performed pretty much up to hopes and expectation in terms of numbers and diversity of insects in this wonderful grassland, scrub and woodland mosaic. Perhaps the Rubicon on the way to ecological calamity has not yet been crossed. Eco-anxiety is such a debilitating condition…

It seems the slow start to the season this year is just that, a slow start. Insect numbers were at last approaching normality, and even if some have been impacted by the extreme weather of the past couple of years, at least they can bounce back just as quickly especially if habitat conditions are suitable. And here is the other bit of very good news: Colchester City Council, whose management of the site over the past few years has been rather erratic, seem to have got on top of the task of ensuring each and every bit of the grassland on Lower Lodge has an autumn cut once every three years, thus preventing life being choked out by the spread of trees. They have thankfully brought it back from the edge of the precipice of such a fate.

It was a  hot and sultry walk, and perhaps the most exciting find came right at the outset with a resplendently metallic Rose Chafer busily chomping on Hogweed flowers. This magnficent beetle is as much a natural icon of the Wivenhoe Area as is the Stag-beetle.

At this very moment, Hogweed is drawing much of the insect life in to its bounteous offerings of nectar and pollen, with for example numerous ladybirds (all Seven-spotted) and a good numbers of Hogweed Bonking Beetles, albeit rather few of them actually living up to the full extent of their name!

The other great nectar and pollen source at the moment is Field Scabious, in fact blooming more profusely and more widespread than I have ever seen it before.

Butterflies were visiting in hordes, Essex and Small Skippers in particular, along with a few of the rare speciality Scabious Longhorn moth, another metallic marvel.

  

But much more as well, from the equally metallic Thick-thighed Beetles, the Gargoyle Fly (our name for Sicus ferrugineus!), green lacewings and various bees, wasps and hoverflies to complete the picture.

Around the meadows generally, but especially along the scrub margins, brown butterflies were also in great abundance. Meadow Browns, now on the wing for the past three weeks, were looking rather worse for wear whereas Gatekeepers, freshly out were more pristine. And the Ringlets so fresh that many were still pumping up their wings after they vacated the pupa in the previous few hours.

Both browns and skippers share one feature – their larval food plants are grasses. And grasses are generally drought tolerant, as anyone who has seen a droughted lawn green up after rain will realise. Perhaps this is why these butterfly groups are doing so well this year, when many others are at a low ebb as a result of last summer’s heatwave?

Other plants in flower included Hedge and Lady’s Bedstraws (white and yellow respectively), Field Bindweed (particularly attractive in their candy-striped form) and the start of the season for Common Knapweed – over the next month this will gradually take over the role of provider of pollen and nectar to a hungry world.

Other plants though are at the end of their season, in particular Goat’s-beard, now forming robust ‘dandelion clocks’. In close up it can be seen how the umbrella-like struts attached above the seed are themselves branched and interlinked, together making a perfect parachute for wind dispersal of the seeds.

Life at every footfall, we saw a couple of grasshopper species and a few other butterflies (here, Small Copper) and moths (including the delightfully euphonious Timothy Tortrix), as well as regular fly-pasts by Brown Hawker dragonflies out a-hunting.

We even paused to examine a few of the galls, with marble and artichoke galls on Oak, caused by wasps, and the lumpy galls of Ribwort Plantain flowers, for which it seems the causal agent has yet to be identified. There is always something to learn in the natural world!

Being so hot, birdsong was only sporadic but included a couple of Yellowhammers, along with a warbling Blackcap and scolding Whitethroats. And it was a present from the avian world which provided a suitable full stop to the morning when one of the group picked up a real treasure, the wing-feather of a Jay.

Of course with all this good news, there is always a bit of bad. and for us that was the lack of any sightings of Common Blue butterflies or burnet moths. Usually regular here, they may yet emerge. Or perhaps, as larval feeders on Bird’s-foot-trefoil, a plant that is badly knocked back by drought, it would not be surprising if this year’s adults are fewer than normal. Neither did we see any sign of the magnificent Purple Emperor I saw holding court during my recce a week ago, nor the White Crab-spider or Hornet Hoverfly I photographed on that occasion.

That is the wonderful thing about the natural world: nothing can be taken for granted, and every foray into it an adventure. All of our previous visits here have had their highlights and lowlights, as you can see from the blogs we have published in the past: see 20212020, 2019, and going right back to the start of #WildEssex 2018.

And talking blogs, this walk was the first with us for one of the group, who told us of her wildlife blog Berie Tree – Nature Spotter! berie tree | Nature spotter! (wordpress.com). Do take a moment to discover it and the lovely observations therein, mixed with poetry and other artistic endeavours. The world cannot have too much of that sort of thing!

The Wild Side of Beth Chatto Gardens: after a summer soaking….

After a June with no rain, good soakings during the first few days of July have brought the garden back to life, made lush and green by that which falls from the sky rather than being reliant on unsustainable, artificial watering.

And the other wildlife too, insects in abundance  – more bees and butterflies than I have seen all summer: the warmth and the recent rain have brought the season back into some semblance of ‘normality’. The plants this week doing the heavy lifting of feeding the hordes of pollinators were Lavandula, Eryngium and Teucrium: good for wildlife, drought-tolerant, beautiful (and therefore good for us) – they tick all the boxes! No words, just let the pictures speak for themselves…

But absolute maestro of our floral show was Buddleia crispa on the side of Beth’s house. Six species of butterfly visiting included four or more lovely, pristine Painted Ladies, one of the welcome stars from the south of any summer garden.

Marvellous Moths morning at Beth Chatto Gardens – early June

It was the first of our new Marvellous Moth mornings in Beth Chatto Gardens. It was early June, the start of the peak season for moths, in terms of both number and variety. Usually! But this year, the seasons have other ideas. The perfect storm: a cold north-easterly airflow for the last six weeks has delayed Spring by several weeks, on top of last summer’s record high temperatures and drought which fried the larvae of many insects, all coming after eight post-war decades of pesticide profligacy … perhaps it is not surprising that the contents of the moth trap we ran the night previously were very meagre.

Of course there were some, but almost all were at the brown end of the normally diverse moth colour spectrum. Most common was the Treble Lines, followed by Common Swift; other species included Heart & Club, Rustic, Vine’s Rustic, Marbled Minor, Flame Shoulder, Small Fan-footed Wave and Light Emerald. In total, a paltry 13 species, totalling some 30 moths. We tried!

But star of the trap show was the single Cockchafer, a lovely large beetle…

Not wishing to dwell on doom and gloom, there are very good reasons why this event was not hugely productive. And the good news is that with luck and a successful breeding season, insect populations can bounce back very quickly, providing the environment is still there for them. And if the habitats are not there in a garden like Beth Chatto’s, essentially organic with a wide range of plants from all over the world providing nectar, pollen and leaf resources, then the planet is in very dire straits.

The other good news for our band of eight visitors is that a shorter time emptying the trap gave us more time to walk and enjoy free-range insects and other wildlife in the garden, first around the main garden in the solitude of that precious hour before the gates opened, and then later around the Beth Chatto Education Trust’s conservation area, away from the public gaze.

Before the influx of visitors, the birds are much more in evidence, and today included Song and Mistle Thrushes, singing Chiffchaffs and Chaffinches, and a fly-through Kingfisher. Several day-flying moths included the Mint Moth, Nettle Tap and disco-dancing parties of male Gold-barred Longhorn-moths…

… while the butterflies were Holly Blues, three displaying couples of Speckled Woods, and a single, resplendent Green Hairstreak, the very first one we have seen this year of a butterfly that often puts in its first showing as early as late April.

As far as other insects are concerned there were several leaf-beetles and hoverflies, Dock Bugs (and their beautiful golden eggs), Two-spotted Malachite-beetles, three species of damselfly, and a whole host of other bits and pieces, including galls (caused by a microscopic mite) on Lime tree leaves, and the interesting case of a case-bearing moth larva.

 

For other caterpillars we were looking at the Mullein leaves, holes in which are made by the beautiful larvae of the Mullein Moth. While much effort and many poisons are expended in lots of other show gardens to present a vision of leaf perfection to the public, in our garden those holes and the mobile adornments are a badge of honour, a sign that our garden is seeking to work with nature and not against it.

And once again, the highlight of this part of the event was a beetle, this time a confiding Wasp Beetle, a dramatically coloured yellow-and-black wasp-alike, its colours evolved to try and dissuade a hungry predator to try and turn it into a meal.

Otherwise we were looking at the plants that were delivering for bees and other pollinators, chance to plan purchases in the nursery to make our own gardens better places for wildlife: Sicilian Honey-garlic, Peruvian Squill, Rock Crane’s-bill, Giant Fennel, Tassel Hyacinths, foxtail-lilies, spurges and a whole lot more…

Do keep an eye on the Beth Chatto website Courses & Workshops – Beth Chatto’s Plants & Gardens if you might be interested in joining us for one of the Marvellous Moths events we have tentatively planned over the rest of the summer. We cannot promise more moths, but we would be surprised if there were not greater numbers and variety, and irrespective, an insect-themed educational wander round the gardens in the still of the morning before the gates open to the public is always a precious moment.

 

The Wild Side of Essex with Naturetrek: late Spring along the Colne Estuary

Although not as sunny as forecast, and still with that persistent northerly breeze that has been niggling away all Spring, today’s exploration of the Wild Side of Essex with a small (but perfectly formed!) group of two provided almost all of what we hoped for.

By late May, as expected, all of the wintering northerly wildfowl and waders had gone, leaving just a few Shelducks (one pair with brand new chicks), Redshanks and Oystercatchers, the latter including our celebrity leucistic friend who has graced us with its ethereal presence for several years now.

Overhead, a couple of Hobbies were high over Wivenhoe, probably terrorising the local House Martins, and as we sat by Alresford Creek for lunch, a Red Kite drifted slowly over, still not a breeder hereabouts but surely only a matter of time…

On the saltmarsh, the Scurvygrass was almost over, so the next suite of flowerers are taking over, including Thrift and Sea Plantain, with Hemlock Water-dropwort in the topmost fringes…

… while the summer crop of Marsh Samphire (Glasswort) is just germinating on the barer patches.

Moving out of from the tidal influence, Hawthorn and Cow Parsley are now at their best, their mingling scents having a special resonance in my brain as my personal madeleine, instant remembrance of my 1970s youth cycling the lanes of the Yorkshire Wolds.

And seemingly every bush adorned with a singing Whitethroat.

Other singers included numerous Cetti’s Warblers, with Reed and Garden Warblers, Blackcaps and Chiffchaffs, Reed Bunting and Yellowhammer, at least three Cuckoos and even one solitary Nightingale. Here in the Nightingale hotspot of north-east Essex, clearly there must be plenty of females as all the rest of our pairs, perhaps five along the route we took, were silent.

The sea walls were adorned with such specialities as Salsify and Spotted Medick, while the coastal grazing marsh, covered in thousands of ant-hills, had Hairy Buttercup and masses of the nationally scarce Divided Sedge.

An assortment of other plants included Red Valerian, Rose Garlic, Tamarisk and the recent arrival to our waterfront block-paving, Four-leaved Allseed, until recently confined to the far-flung reaches of Cornwall and the Scilly Isles.

Our afternoon took us from the coastal plain to the heights of the Essex Alps. This shift from clay to gravel introduced a whole lot more plants, including Hop Trefoil, Slender Thistle,  Heath Woodrush and Bird’s-foot Clover.

Dog Rose is just coming into glorious flower, while Beaked Hawk’s-beard was doing the heavy lifting of feeding the (few) insects flying around…

…while Purple Gromwell is now at its absolute peak along Cutthroat Lane.

Moving into the ancient woods of Cockaynes Reserve, a whole new suite of plants appeared, including Climbing Corydalis, Pignut and Common Cow-wheat, all very scarce in these parts.

So what of the insects? Well, as is sadly the new normal, rather few. A few soldier- and click-beetles, a Red-headed Cardinal-beetle, Brown-tailed Moth caterpillars and a Latticed Heath moth were just about all we could muster.

Apart from all that, several galls, including Oak-apples and Sloe Pocket-plums, and a patch of the Grass-choke fungus all added interest to a lovely, diverse day out.

But as an uneasy coda, just one butterfly (a Small Heath) and not a single dragonfly or damselfly. Yes, the cool breeze,  the late Spring and last year’s extreme drought and unprecedented temperatures must take some of the blame, but I cannot help fear that we are heading for the Silent Summer, the result of our unsustainable impact upon our world. Our only world.

The Wild Side of Beth Chatto Gardens: a Great Awakening…

There comes a time in any year when the passage of Spring suddenly accelerates into a headlong tumble into Summer. Today was that day in the garden. Held back for so long by the April cold winds and gloom, today the celebration of life and the new season was palpable. Aided by the stilled air and the humidity which culminated in some very spiky showers and ferocious grumbles of thunder, bird song was everywhere, from warbly Wrens and Blackcaps, through wheezing Greenfinches and tinkling Goldcrests, to a stately Song Thrush and the most beautiful of all, several joyful Blackbirds.

Insects, for the first time this year, were everywhere. Six species of butterfly included lots of Orange Tips and our first Speckled Wood and Holly Blue of 2023. But much more of interest, many of which again were the first we have spotted this Spring, from bugs…

… to damselflies, a tiny first-instar bush-cricket nymph, a scorpion-fly and Alder-flies…

…. and a whole array of spiders, beetles, wasps and flies.

But more than the creatures, today’s walk was full of the sights, sounds and smells of a world reawakening from its slumber. Plants, floral vistas and whole landscapes vibrant in the sporadic sunlight, the spring oak greens rendered especially dramatic by the smoky blue backdrop of thunderclouds.

Spring is likely to be telescoped this year as a result of its late start and the heat that seems to be heading our way from Iberia: enjoy it while you can. And where better to do so than in the Beth Chatto Gardens. A place for plants and for people, but also a haven for well-being and wildlife!

#WildEssex – Wivenhoe’s Barrier Marsh and its anthills

We have visited Barrier Marsh many times on our walks, and always marvelled at the number of ant-hills covering it in low, grassy hummocks. Indeed we have blogged about the ant-hills before, most notably here, right at the start of the pandemic.

Each hill is different, a microhabitat of heathland amidst the marshy matrix, and they also change markedly as Spring develops. This time last week, the hills were just starting to redden under the influence of Sheep’s Sorrel; today, its red glow was spreading widely…

Many of the hills were picked out in white with the last flowers of Common Whitlow-grass, really a March speciality though somewhat delayed by our tardy spring, and by the newly emerged Sticky Mouse-ears, and on just one hill we found, Small Mouse-ear.

Blue was added to the palette by copious amounts of Wall Speedwell and a little Thyme-leaved Speedwell…

…while Early Forget-me-not, in many years a real feature of the dry ant-hills was restricted to patches on the sea wall, perhaps a reflection of our wet Spring. But is was a delight to see its close relative Changing Forget-me-not on again just a few hills, a species we have not noticed previously here although it is abundant on the sandy peaks around Cockaynes reserve.

Much less obvious, but only on one hill each so far as we could find was Mousetail (the same hill on which we found it a couple of years ago), also known in one place from cattle-poached ditch-sides on the marsh itself…

…. and so insignificant we couldn’t re-find it today, one small plant of Blinks. Again, this was a new record from the marsh as far as we are concerned, although common on the open sand heaths of Cockaynes.

All of these were of course set amidst the wider damp grassland, with Daisy and Bulbous Buttercup, Meadow Foxtail grass just coming into flower, and whole swathes of the nationally-scarce Divided Sedge.

Away from the marsh, on the sea wall and the Wivenhoe Waterfront a whole new set of plants are now belatedly coming in to flower. Several are ‘little pink jobs’ , perhaps confusing initially, but each with distinct foliage or floral features: Common Stork’s-bill, and  Dove’s-foot, Cut-leaved, Round-leaved and Shining Crane’s-bills.

White Ramping Fumitory and Alexanders are starting to fade, whilst Spotted Medick and Cornsalad are just emerging, with English Scurvygrass out on the saltmarsh, the start of flowering in that habitat, something that will support a changing floral mix right through until autumn.

Our walks were accompanied by the sound of singing Cuckoos, Cetti’s Warblers and Whitethroats, but sadly insects were few and far-between. However, the first Small Copper and Orange Tip of our spring signalled that season is unfolding, and on the sea wall Sea Beet, our favourite Neon-striped Tortoise-beetles have emerged a good couple of weeks earlier than in previous years.

Otherwise, a small but motley selection of invertebrates kept us searching and interested…

…. perhaps the highlight being a zombie ladybird, hiding and indeed protecting its nemesis, the parasitic wasp Dinocampus, that has been eating out its body contents but is now pupating under the paralysed body.
