Gunnersbury Triangle Damselflies Egg-Laying Like There’s No Tomorrow!
Sparrowhawk drives Squirrel from Nest!
The day looked unpromising for a nature walk, let alone a butterfly transect, but it was time to do one, so after a cursory tour to clip the worst of the brambles from the paths, we set off with clipboard and cameras to see what we could find.
The hogweed, still in flower despite weeks of rainy weather that has caused many stalks to topple, was alive with flower beetles, bees large and small, and this magnificent Ichneumon wasp with its incredible ovipositor.
At first we saw only white butterflies, but a Comma was sunning itself, and a Speckled Wood had somehow survived the wet weather.
We saw two Strangalia maculata longhorn beetles taking nectar. They are Batesian mimics of wasps, looking in all truth only very slightly waspish, but perhaps young birds are put off. Or perhaps they do in fact taste foul.
We were just discussing the Sparrowhawks as we approached their nest tree when a commotion broke out along a branch, and a Sparrowhawk flew rapidly with its claws forward: a Squirrel raced away from the nest, hotly pursued by the angry bird; they leaped to the neighbouring tree and scurried up the matching branch out of sight. The Sparrowhawk broke into a loud excited chittering trill. We were all excited, laughing at the speed, the impossibility of reaching for a camera.
A Holly Blue flew over the pond, above several pairs of mating Azure Damselflies and a Yellow Iris now chewed right down to a semi-leafless state by the Iris Sawfly larvae.
Down at the Anthill Meadow, a single Small Skipper perched on an ear of Yorkshire Fog.
On the next ear was a male Bluetail Damselfly: they have emerged from the pond in the past week.
The wooden rail was sticky with snail pulp: a Song Thrush had hammered three snails open on the exposed woodwork, leaving shells and sticky patches behind.
Two days ago I saw a Cinnabar moth in the Small Meadow. There is plenty of Ragwort coming up, so with any luck there will be plenty of caterpillars soon.
This Week’s Insects at Gunnersbury Triangle
Comma, Red Admiral, Small White, Meadow Brown, Holly Blue, Speckled Wood butterflies this week. A Cinnabar Moth, the first of the year, flew over the bank near a patch of Ragwort, the food plant of its caterpillars. Let’s hope she laid some eggs.
The first Bluetail Damselfly appeared today; Azure and Large Red Damselflies still about.
Mayflies Rising!
May is the fastest time of Nature’s year. What a difference a few days make! Last time at Wraysbury, a few sluggish mayflies sitting around as if waiting for something to happen in a one horse town.
Well, today it’s happening. In places, the sky is filled with rising mayflies: a few mating, most alone. Here and there, some repeatedly dance up, and a few seconds later, down; but most just climb, and fly about, seeming frail on their large wings, their triple tail streamers hanging below them: it’s worth zooming in on the picture. Even better, here’s a short video clip. The soundtrack combines an airliner taking off and a Blackcap singing.
One of the glories of summer by water is the brilliant turquoise and green iridescence of the male Banded Demoiselle – the so-called band is actually the appearance of flickering of the wings, the dark spot on each of the four wings giving a hard-to-describe semblance of a sparkling blue jewel in flight, with bands of colour too fast and changeable for the eye to understand. But he’s pretty fine at rest, too.
Common Blue, Bluetail, and Red-eyed Damselflies have all now emerged, the Red-eyed being the scarcest of the three, seemingly.
On the Cow Parsley were, as well as the damsels, two cantharid Soldier Beetles, Cantharis rustica or a close relative. Another enormous cloud of rising mayflies, and suddenly behind them a pair of Hobbies, hawking for insects – whether damselflies or even mayflies is impossible to tell. One comes close, wheels away on scything wings as it sees me.
A Silver-Ground Carpet Moth, Xanthorhoe montanata, flutters weakly past me among the Hawthorn bushes and flops onto the grass. Garden Warblers sing, a Whitethroat rasps in its songflight. A Treecreeper sings its little ditty sweetly from near the river.
On the hill, three Greylag and two Egyptian Geese form a peaceful flock. Stock Doves and a mixed flock of Crows and Jackdaws rise from the grass. A Song Thrush gives a marvellous solo recital near the road.
