A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

Winterton mothing

Saturday 19th August was the night of the Norfolk Moth Survey event at Winterton.  I went along hoping for some good moths but the conditions were quite breezy so not ideal.  We still had a good time though.  There were no new moths for me (actually Stuart showed me leafmines of Sandhill Midget Phyllonorycter quinqueguttella which I've not seen before, but I don't count leafmines, especially vacated ones) but we recorded a few interesting species.

We'd hoped for some migrants and did indeed have a nice haul of 5 Scarce Bordered Straws, a species I'd only seen once before - but some variety on the migrant front would have been nice.  There were 6 White-points and a Diamond-back Moth but I'd been hoping for something a bit more interesting.

There were plenty of highlights though, including Hook-tipped Grass-veneer Platytes alpinella, Long-legged Tabby Synaphe punctalis, 13 Chevrons, 2 Peacock Moths, 6 White-line Darts, Coast Dart, 15 Archer's Darts, 10 True Lover's Knots, Dotted Clay, 2 Gold Spots and 2 Red Underwings.

The only caddisflies I noted were 3 Limnephilus marmoratus.  This weevil proved to be a new species for me, Hypera zoilus.

I was uncertain about the ID of this leafhopper - it resembled Mocydiopsis attenuata but the length of the final abdominal segment seemed a good match for the photo on British Bugs of Mocydiopsis parvicauda.  That species normally lacks the dark spot in the clavus which this one had but the text in the website implied that it could possibly have the dark spot sometimes.  So I contacted Tony Irwin, an old friend and county recorder for leafhoppers among other things.  He noted a resemblance to Mocydiopsis intermedia, a species not recorded in Britain, but he was at pains to point out that it would probably turn out to be less exciting.  He later examined the insect for me and confirmed that it was Mocydiopsis attenuata - so not quite as exciting as a new species for Britain but perhaps still the best record of the night as Tony thinks it was new for the vice county.
