A sunny but not particularly warm day, +17° C. Been to Mill Hill nature reserve near Shoreham-by-Sea, in West Sussex. I have serious concerns that the place may pretty soon drown in dog shit :\
Wall Browns (Lasiommata megera) are flying, although in lower numbers than last year — but are absolutely impossible to photo.
Gold-fringed Mason Bee (Osmia aurulenta), a mainly coastal species in Britain:


Dingy Skippers (Erynnis tages) are quite common:

Been to Mill Hill nature reserve on the South Downs near Shoreham-by-Sea in West Sussex.
Wanted to find the Wall Brown (Lasiommata megera) there, which apparently may still linger in that place, despite a widespread extinction in Southern England in the last decades. Didn’t see any =(
Anyway, it is a very nice chalk downland location, with plenty of wildlife — although it is a bit more popular with dog walkers than I prefer.

Heard (not seen, but pretty sure about it, I am very familiar with the species) a Wart-biter (Decticus verrucivorus), never met with this big guy in Britain before, it is ridiculously rare here!

Lots of butterflies at the place.


Hemp Agrimony (Eupatorium cannabinum) is the number one butterfly attraction. Painted Lady (Vanessa cardui) agrees:

Southbourne and Chichester harbour

Been to Southbourne in West Sussex, went to the Chichester Harbour nature reserve near Thorney Island.


I know about this place from back in 2007, when John Langmaid, a prominent British lepidopterist, led a field meeting there. Nine years had to pass until I got there again.

Most of the saltmarsh is now fenced off, probably due to various birds nesting there. The flagship of the place though, lives not on the saltmarsh but nearby: it is a casebearer moth Coleophora (Multicoloria) vibicella, which feeds upon Dyer’s Greenweed (Genista tinctoria), a rare plant in Britain by itself. Both are common at Chichester Harbour, though.

I had collected a number of C. vibicella cases back in 2007 — got shitloads of parasites from them, but no moths!
I’ve collected some today — and all I need now is sheer luck, I suppose…

The case is huge for a Coleophora (about 20mm long), and conveniently resembles its foodplant’s seed pod:

Misguided by the morning sun, went to Brighton today. Wanted to find the Wall Brown (Lasiommata megera), but it turned cloudy in the afternoon, and most butterflies didn’t show themselves.


Saw a few Clouded Yellows (Colias crocea), though:
