Cream-bordered Green Pea trapped at Dersingham (2nd site record)
(Connor) Trap highlights for 24/7/07 at Dersingham:
Light Arches,
Swallow Prominent,
Lesser Swallow Prominent,
Sallow Kitten,
Slender Brindle,
Diamond-back Moth,
Bloodvein,
Pebble Hook-tip,
Cream-bordered Green Pea.
Trapping in general this year has been poor with poor quantity and quality of resident species and the only immigrants being about a dozen Diamond-back Moths. This trap was an improvement especially in terms of resident species.

(James) This micro turned up at Bates Wood a few nights ago (i'm only photographing pretty micros, not the crummy old grey ones, so don't worry I haven't fully lost my mind yet). Anyway, thanks to Peter Tilley of Holme and Jon Clifton of Anglian Lepidopterist Supplies it turns out that Evergestis extimalis (the micro in question) is an occasional wanderer from the Brecks, and not especially common, so it is a pretty decent record!

(James) The first trap on Stow Estate was fairly decent, especially considering the rain throughout the night, producing about 50 moths of 20 species. Highlights included several Black Arches, Slender Brindle, Bordered Beauty (top), and 11 Poplar Hawkmoths (bottom) - the largest number recorded by me in one trap!
(James) Small Phoenix and Grass Emerald at Bates Wood. The 7 consecutive traps I have just conducted there for my Biology coursework reeled in 807 individuals with 95 species (excluding the ones that got away!), adding between 10 and 20 new species to the Denver list! Species diversity calculated from the samples using Simpson's index produced a value of 20.8 - I now have another 7 days trapping at a pine plantation on Stow Estate to compare these data.
