Field Trip - Hexton Chalk Pit - 25/05/17

Thursday night saw me trapping at Hexton Chalk Pit for the first time this year after doing a few daytime forays for moths and finding a few bits and pieces, it was time to go all out and spread 5 traps over the reserve. I was joined by Trevor for a bit and Tony popped by to see how things were going.

The day had been very warm and sunny and mid-twenties by 4pm, there was however no cloud cover but with a warm breeze it was hardly going to get cold and in fact it was still 14 degrees at 2am when I left the reserve. The traps out of the breeze did fair better and by midnight, the exposed trap on the chalk hill did take a pounding and most of the moths ended up about 3 metres from the trap having been blown there.

Numbers were pretty good and the species kept coming in, heck if I had stayed until dawn I probably could have added another 15 species I reckon but I had work the next day and getting to bed at 2.30am was late enough!

Some cracking species were netted before the lights were turned on, Bucculatrix bechsteinella (only my second ever), Elachista biatomella (new to me and a rare moth in the County only having one previous record), a shiney green moth which is the uncommon Eulamprotes unicolorella and Rhopobota stagnana (another new moth to me).

I joked to Trevor that we may as well pack up now after the successful half an hour of sweeping!

Other good moths that later came to the lights were Wood Carpet, Netted Pug, Anania fuscalis, Alder Moth, Marbled Coronet and Satyr Pug.

The best moth for me if correct would be Syncopacma sangiella, Graeme will look at it and if it is it will be a County first record.

It was also very pleasing to see that Anania fuscalis is still hanging on there after re-discovering it 181 years later in 2015.

Still reeling from seeing so many moths and I hope to be back in a few weeks.
