Hexton Chalk Pit - Field Trip - 01/07/14

Roger and myself ran 3 traps at Hexton Chalk Pit on Tuesday evening, with Steve turning up at dusk for some moral support and staying with us until midnight. The reserve is a lovely habitat with a multitude of wildflowers growing on the chalk grassland. There are patches of bare chalk, but there could be more, as Bramble is starting to take over certain areas of the chalk grassland. The day had been mild and breezy with a high of around 21 degrees, but by dusk the sky was still crystal clear and the breeze was on the cool side and coats were worn pretty much from the off in fact hats wouldn't have felt out of place! with a low of 8 degrees when I was on my way home at 3am we were totally blown away by what we did manage to catch...

For starters I managed 3 new Macro moths for me, Grey Arches, Reddish Light Arches and Royal Mantle (previously seen in Slovenia for the first time).

Even better were some of the Micro's that turned up

Firstly we had two Agonopterix liturosa, which currently is quite scarce in Herts with a handful of records.

Secondly we had I would say 20+ of the Pyralid, Paratalanta hyalinalis. I had two, but one escaped whilst photographing them, typically only a photo of a battered one. One is with Roger. No records since 1937, confirmed! And a very good moth indeed.

Other notable species included Satyr Pug, Dark Umber, Shark and 5 Wood Carpets (Only having previously seen one before, to record 5 in a single trip is quite overwhelming).

On the Pyralid front we got Paratalanta hyalinalis in great numbers, along with 5 Ebulea crocealis and 5 Sitochroa verticalis.

To round this post off, the session was an incredible insight in to just how important this habitat is despite it's small size and relative remoteness.

A micro-climate indeed... I shall be going back!
