Wicken Fen - Field Trip - 23rd May

I was invited to trap at Wicken Fen for a mini blitz of two areas at once, Adventurer's Fen to the South-west of Wicken Fen, and several trappers also around Sedge Fen and visitors area.

I was just to the south of the visitor centre, positioned with 4 traps primed and ready for the arrival of moths.

I did a bit of dusking but there were very few moths that I saw flying, as it was fairly breezy at time. Tapping a few trees and bushes dislodged a couple of specimens to the back of the net, but the night soon closed in and the traps were on.

Two of the traps were a bit exposed and did not fare very well, I opted to close down the actinic trap as it was just full of flies and only a couple of moths seemed interested.

But the 125w clear near the car park area did very well for variety, even better though was the trap that never lets me down, the 250w clear robbo.
Most of the nights moths and species came to this lamp and by the time I packed up at 2am I had amassed an incredible 157 species, for May this was very pleasing indeed.
 
Highlights included several Dentated Pug, one was pretty fresh and good to see, as all my previous ones have been battered.
15 Poplar Hawk-moth was a nightly record for me. 
 
There were surprises of fresh Clouded Drab & Powdered Quaker, both are my latest ever records, and looked particularly funny flying alongside Elephant Hawk-moths! 
 
There were also a few migrants present including one Delicate and five Small Mottled Willows.

Best moth of the night were two examples of the tiny Vine Moth (Eupoecilia ambiguella) sadly both a bit worn.

A nice selection of moths and good to get together with a few other fellow trappers.
