Phew!  What a scorcher!  Thank you to the participants of today’s Botany and Bug walk at Lower Lodge, and hope that you enjoyed seeing what is surviving this almost unprecedented dry spell: our last walk six weeks ago followed the last rain recorded in these parts, with no more than a hint of it in the next two weeks’ forecast….

Amazingly a lot is hanging on, and in fact doing rather well considering.  The uncut swathes are full of plants and alive with insects.  A vast contrast to the desert-like parched areas of mown grass.  A lesson to us all in what we can do to help the continued survival of our natural world: natural habitats have natural resistance against environmental stresses.

Insects were out in number and love was certainly in the air!  We rather voyeuristically watched the ‘goings on’ of  various pairs – the stunning Black-and- Yellow Longhorn-beetle; Common Red Soldier (aka Hogweed Bonking) Beetle; and the totally differently positioned Forest ( or Red-legged) Shield-bug.  Following on from this theme, a rather beautiful cache of ladybird eggs was seen glinting in the sun.

Other creatures of interest included several species of butterfly; two sorts of skipper; a long-horned moth;  plus both 5- and 6-spotted Burnet Moths. The egg cases of these beautiful day-fliers are curious affairs, and we were lucky enough to see one clinging to a grass stem.    Caterpillar fans were delighted to see the yellow-and-black Cinnabar Moth larvae out in force, chomping their way through poisonous Ragwort.  In addition a selection of ladybirds, spiders, bees and grasshoppers  made for a varied couple of hours.

We were aware of the presence of microscopically small creatures too – in the form of galls (abnormal growths caused by something living in or on the host plant and causing its cells to enlarge and provide shelter and food for the gall-causer). Oaks are particularly interesting where galls are concerned – in fact in the UK various kinds of Oak support over 50 different kinds of them, on leaves, buds, stems, acorns and sometimes on the trunk. We saw a few of these today – the artichoke;  ram’s-horn; marble; knopper and spangle-galls.  Others were no doubt there had we had longer to search.  And it wasn’t just the Oak, Willows too supported a variety of gall-causing insects and mites.

On the plant front, a favourite was Wild Carrot – an umbellifer loved by many kinds of insect.  The variety we encountered has a tiny red flower in the middle of each umbel which acts as an attractant to other insects to ‘Come on Down and check out my pollen’.  The Jack-Go-to-Bed-At-Noon flower had indeed gone to bed very early, and most were now in rather beautiful seed-head form. Bird’s Foot Trefoil and Scabious provided some colour and we were all interested to listen  to the popping seed heads of the Tufted Vetch.  These were exploding in the heat and dryness, popping their seeds into the air to propagate for next year. Who said plants are silent?

’41 Acres’, ‘The bit behind the Allotments’, ‘the southern end of Wivenhoe Heath’, whatever you like to call it, was certainly an interesting venue for our June’s Botany and Bug walk. Thank you to everyone who joined us, especially the hay-fever sufferers who found it challenging but nevertheless enjoyable…

The main reason for hay-fever stress was pollen from the many and varied grasses which inhabit this area – land formerly gravel pits but which is now filled in and in recent times been allowed to do its own thing. On an early summer morning, slightly damp and very humid it was certainly lush and fertile, but slightly worryingly, unless this land is managed, it is in danger of becoming too overgrown and losing its wildlife interest.

So, what did we see? The aforementioned grasses, with their wonderful English names – the peppery-tasting False Oat-grass, Cock’s-foot and Yorkshire Fog – were all looking splendid.

Pretty pea-flowers of various types were easily spotted, including tares, vetches, medicks and the beautiful Grass Vetchling.

A botanical highlight had to be the Southern Marsh-orchids, maybe thirty of their purple spikes visible among the dense undergrowth. This is one of the species that will eventually be pushed out if nothing is done to control its neighbours, as has probably already happened to some of the other orchids found here until three years ago.

Insects were out in force. The brightly-coloured Cardinal beetle was easy to see, but other more camouflaged beasties were equally interesting: the rather peculiar European Cinchbug family clinging to a grass leaf, the bagworm moth encased in its suit of dead grass stems, and the unidentifiable but undeniably cute saw-fly caterpillar.

A couple of species of ladybird were noticed – a tiny vegetarian 24-spot, one of the smaller types, and in contrast the much larger Harlequin, a voracious eater of aphids, but unfortunately also other ladybirds. Watch out Mr 24 spot!

Thick-thighed Beetles were looking polished and sparkling in the sunshine, but the piece de resistance had to be the fabulous Fox Moth, spotted  by Glyn.

Our next walk will be on Sunday 15th July – a different date to that advertised, (we wouldn’t want to compete with The Tendring Show), at Lower Lodge.  Meeting place will be the Outdoor Gym, easily accessible from Dixon Way, or the railway crossing from the trail, or the Rosabelle woodland car park. If you would like to book a place, please contact Jude (jmgibson1959@btinternet.com 07503240387).  Looking forward to seeing some of you there.

Another very enjoyable Botany and Bug walk this morning, and our thanks to all of you who were able to join us.  The perfect sunlight enhanced the landscape, with a multitude of green hues on the foliage as well as the splendid sparkling water and shining mud banks.

 Much of the flora on show is very relevant to our part of the coast, including the Scurvy Grass and Thanet Weed, salt-tolerator and invasive plant which arrived through the ports of the south-east respectively.

The Rose Rust fungus, not seriously damaging to the host plant, was a very colourful addition to the morning. Once we entered the shady wooded part of the walk, the flora changed to include Yellow Archangel, Herb Robert and of course Bluebells.  The native Bluebell was in abundance at Grange Wood, and close examination revealed cream pollen on the stamens. The larger Spanish Bluebell, so common in gardens and a risk to our native species through genetic pollution, has blue pollen, which is one way of telling the difference!  Another is the difference in distribution of flowers around the stem: natives have flowers on one plane, whereas the Spanish are placed all around the stem.

 We were of course also on the lookout for bugs and beasties, and search was rewarded with the splendid Squash Bug.  St Mark’s Flies -all dangling legs and fearsome-looking, but entirely harmless – were on the wing in fine number, many feeding on umbellifers, and others, less fortunate, entangled in spider’s webs awaiting their certain fate.  A field day for local spider population!

Several nests of the highly-irritant Brown Tail moth caterpillars were seen.  Although interesting to observe, it isn’t recommended to touch the insect as a nasty rash may result.  As with all wildlife, respect is the key. And remember, they are a good food source for one of out most loved birds, the Cuckoo. 

On the way back some of us were fortunate to espy a Large Red Damselfly basking and soaking up the sun. The first damselfly of the summer, and hopefully a sign of a good one for weather and wildlife alike.
