More synchronisation

Grasses can be incredibly difficult to identify, but fortunately - once the initial identification has taken place - many can be readily identified in the field. This is Meadow Foxtail - Alopecurus pratensis:

And this is Sweet Vernal Grass - Anthoxanthum odoratum, which gets its name from its sweet smell when dry, and also from the fact that it is one of the earliest grasses to flower:

Of course, as soon as those fresh new leaves are available, the parasites move in. This is the rust Puccinia graminis on Meadow Foxtail:

Now that the sun is out again, micromoths are making an appearance. This is Ancylis badiana, about 10mm long:

The micromoth Ancylis badiana

The larvae of Ancylis badiana feed on various members of the pea family, including clovers and vetches. The larvae of the following species of micromoth, however, are unknown.

Micropterix calthella is always to be found in or near Meadow Buttercup. Adults are 4mm long.

I watched this specimen as it wandered over the flower and then posed in profile. Note the wonderful yellow tuft of hair, like a wig:

Given the adult moth's predilection for Meadow Buttercup, I'd guess the larvae live on the roots of it.

As I was walking along, I felt a tickle on my arm, and I immediately thought "It's too early for midges". I rattled off a couple of shots of the microscopic beast and was delighted to find this minute (2mm) Chalcid wasp struggling through the hairs on my arm. Chalcids are tiny members of the Ichneumonid family, parasitising micromoths and other small insects.

Note the very sparse wing venation, which is a feature of Chalcids, and also the dark triangular pterostigma, which is a feature of ichneumonids in general.

Staying with parasitisation, I found this 'mummified' aphid on Cow Parsley. Aphids which are inflated and glossy like this have usually been parasitised by a member of the Aphidius family of Braconid wasps, which are yet another branch of the ichneumonid family:

Ferns are all unrolling, now. This is Scaly Male fern - Dryopteris affinis:

Ferns are a major component of the hedgerow, providing food, shelter, display and basking opportunities for many insect species.

Mixed bag

These are the last photographs from my usual stretch of hedgerow for several months. The day after I took these, the hedge was cut down to the ground to a distance of a metre from the road on each side for 200 metres. So there won't be anything worth posting from there until next spring. I don't know why the hedgecutter chose this totally inappropriate (and illegal!) time to do the cutting ("it's only weeds and bugs"), but we have to live with these decisions. Unfortunately, the wildlife can't.

Last year I showed a photograph of the capsid bug Lygus rugulipennis. This is its nymph from exactly the same area:

If you follow the link back to the original picture, notice how different the adult is from the nymph. This is typical in bugs, and makes identification of nymphs that bit more difficult, since it's normally the adults that are shown.

Udea lutealis is one of the larger micromoths, and is to be seen on practically every verge and hedgerow at the moment. The faint pattern diminishes as the moth gets older, and mature specimens (i.e. a few days old) appear to be a uniform cream in colour:

I spotted this larva of the Sawfly Arge gracilicornis on Bramble. I had hoped to follow its progress for a few days, but that is no longer possible:

Larva of the Sawfly Arge gracilicornis

I should also mention at this point that I will be unable to continue my 5 year study of the sawfly Nematus pavidus this year, since the Willows were also threshed to ground level and won't have leaves until next year. I hope I can find some more specimens elsewhere.

The fungal rust Puccinia graminis infects many different grasses. This infection is on a stem of False Oat grass:

I haven't seen very many specimens of the wasp-mimicking hoverfly Sericomyia silentis this year. This one was on Male Fern on the other side of a deep ditch:

Hoverfly Sericomyia silentis

Earwigs are universally despised and, I think, a bit unfairly. They are quite unusual in that they tend to stay in family groups, whereas most other insects abandon their eggs/larvae. This is a male (the pincers are curved) Forficula auricularia:

The earwig Forficula auricularia

This one was photographed in my garden: I found it when checking a pot full of Fuchsia cuttings. Notice how small the wing covers (the squarish area next to the middle leg) are. Earwigs can actually fly, but I rather suspect that they are reluctant to do so because the wings have to be folded around 40 times to get them into such a tiny space.

New identification.
