Field Trip - Ashwell Quarry - 22/05/17 On Monday night and after a really warm day peaking at around 25 degrees, it was off to Ashwell Quarry with traps in tow.

Trevor and myself set about setting up all of the lights spread across the reserve covering nearly all of it. We did a little bit of 'dusking' before it was time to switch the lights on and turned up a few micros, notably Cauchas fibulella (Is this moth on every patch of Germander Speedwell in the County of does it just favour chalky areas where the plant seems to flourish?).

The night started well and we had a bit of cloud cover to boot, but that did disappear eventually to leave a large clear sky and a slight drop in temperature to 13 degrees by 2am. The thing that did hamper us slightly was the fact that the wind got up a bit as the night went on.

It was good to get Netted Pug which is still a scarce moth in the County and cracking to look at, also Trevor saw his first ever Pseudargyrotoza conwagana, a pretty little tortrix moth.

Also a Geometer had us really stumped. To Trevor's trap we potted up a dark grey Emerald looking species, which after much searching of books and the web I finally settled on the rare 'nigra' form of Blood-vein, minus the vein marking and with a hint of 'blood' along the fringe of the forewings

There a few outstanding specimens to be gen det, a Cochylis species and a Scrobipalpa species.

Generally numbers were a little down on what we had hoped and we didn't quite get to the target of 100 species but nevertheless some good fresh specimens were observed and it was a pleasure to just get out there and give it a go!
