Other half-decent moths included Hawthorn Bent-wing Bucculatrix bechsteinella, Lead-coloured Drill Dichrorampha plumbana and my first migrant at the meadows, a Silver Y.

I counted at least 32 Cocksfoot Moths Glyphipterix simpliciella but they were everywhere and I expect I'd have found hundreds if not thousands if I'd looked hard enough. Other moths were Plain Gold Micropterix calthella, Hawthorn Slender Parornix anglicella, 6 Common Nettle-taps Anthophila fabriciana and Red Twin-spot Carpet.

There were 2 Dock Bugs and my first 2 Red-and-black Froghoppers Cercopis vulnerata for the site. Also a Leptopterna nymph, I suspect dolabrata but I don't think you can rule out ferrugata at this stage (let me know if I'm wrong about that).

Two beetles were both completely new species for me. I've not been doing beetles that require microscopic examination for very long so new beetles are quite a regular feature for me, but one of these was a ladybird, the distinctive examples of which I have been identifying for quite a few years, so a new ladybird is a much more satisfying and exciting find. It was a 24-spot Ladybird, a species with a scientific name that's way too long: Subcoccinella vigintiquattuorpunctata, though I see some sources transcribe it simply as Subcoccinella 24-punctata.

I don't think it's especially uncommon, but uncommon enough for me not to have noticed it before. The other new beetle was one that required close examination, indeed I think I may have seen it before and misidentified it even after microscopic examination. I eventually figured out that it was Polydrusus cervinus, a species that, unlike several other similar species, is not always a metallic green colour. I was initially put off by its colour, thinking it must be one of the other Polydusus or Phyllobius species but in the end cervinus seemed to be the only species that ticked all the boxes, and it turns out they are quite often this green. One or two of the other features were quite hard to see too, and I wonder if I may have got these wrong in the past as they're meant to be very common indeed.

Hoverflies included another Melanostoma mellinum and a new species for me, Sphaerophoria interrupta.

I found a number of ants on a tree trunk and then swept some more off some nearby Common Vetch. I was sure they were not one of the two species I'd identified up to now and sure enough they proved to be Negro Ants Formica fusca. There was also a Common Red Ant Myrmica rubra among them.

Bees included Flavous Nomad Bee Nomada flava, Red-tailed Bumblebee and Common Carder Bees.

This spider seems to be Tetragnatha montana I believe...

Some nice flowers too, including these Hedgerow Cranesbill and Star-of-Bethlehem.

A while ago I posted about an algae-covered larva I found at Bittering on 13th April. I'd initially identified it as either Virgin Bagworm Luffia ferchaultella or White-speckled Bagworm Narycia duplicella, both of which have similar algae-covered larvae. For reasons that I can no longer recall or fathom, I eventually plumped for the former and recorded it as Luffia ferchaultella.
It soon ate all the algae on the bit of bark I collected it on, so I returned to gather some more and put it in the pot with it. After a few days it stopped munching and remained still - I wasn't sure if it had died or pupated, but kept it sitting on my desk and checked it daily. On 19th May I looked again and noticed a change - protruding from the tip of the case were what looked like clear wings. There was no sign of life though and I wondered if it had died on emergence - I hadn't at that point noticed any live insect in the pot. I checked a bit harder and was pleased to see a moth sitting still on the bark. Now Luffia ferchaultella is a parthenogenetic species and only wingless females are known. This insect had wings, so it wasn't ferchaultella after all - it was Narcycia duplicella. Anyway a first for me, not only a new species but the first time I've ever successfully reared a moth from a larva.
