Guernsey

I thought I was making rapid progress until I saw the other guys' lists and realised I've been somewhat pedestrian.

425 - Garden Carpet
426 - Cockchafer
427 - Flame Shoulder
428 - Cabbage Moth
429 - Heliophanus flavipes (spider)
430 - Dryadaula pactiola (moth)

This is easily the rarest thing I've found so far on the challenge. There appears to be only a handful of British records of this adventive species. More details on my blog (here).

438 - Fern-grass
439 - Cacopsylla fulguralis (psyllid bug, abundant on Elaeagnus)
440 - Stenodema laevigata (grass-bug)
441 - Tingis cardui (Spear Thistle Lacebug)

And a couple of things people may be able to help with the ID of :

Have struggled to pin down the ID of this weevil using the books. Was trying to ID as a Phyllobius but then noticed on the net another species, Pachyrhinus lethierryi, which occurs on conifers, under which I found this. Suggestions welcome.

These black-coloured flies seem very common at the moment.
