Hemel Hempstead Field Trip - 11/06/13 David Kirk, Roger Prue and myself made a trip to two of the Boxmoor sites in Hemel Hempstead. The evening looked absolutely perfect for moths with cloud cover expected throughout the night and a minimum of 13 degrees, though when I arrived at the first site at Gadesprings the cloud had promptly vanished. We set two traps up at Gadesprings and left them to their own devices, then we made our way to Bovingdon Brickworks where we would setup 2 more traps running from a generator. As we started to setup, more cloud had developed and the wind had dropped so we were confident of getting a few moths. The moths were as always few and far between at the light first, but then as the night went on, at about 10.30pm we were seeing much more variety in singles, with just a few moths having an influx, notably Green Carpet, Silver-ground Carpet and the micro Monopis weaverella. We packed up at about 1.30am at Bovingdon, and it took awhile to count everything....species were still flying in and god only knows how many we would have recorded had we stayed until first light. Of the two sites, Bovingdon did the best, but what we didn't expect was to find a further 24 species at Gadesprings that did not feature in the Bovingdon catch. Strangely and in keeping with this odd year, one of the commonest moths was Nut-tree Tussock, in which we recorded 4 to the 80w Actinic and 1 to the 125w MV. This is a very late record, considering a few of them were fresh. We did not get Poplar Hawk-moth, which was pretty much expected from Gadesprings. Notables of the night were moths new to myself, Mompha raschkiella, Strophedra weirana and Elachista atricomella, May Highflyer was also a seldom seen moth.

All in all we had an incredibly enjoyable night and would like more of these please Mr weather!

Of all the moths identified, there is only one we are struggling with, which will have to be omitted as it is too worn and dead apparently!

The jet black Prays fraxinella/ruficeps will have to be checked by Colin Plant, I did confidently predict one of these, judging by the amount of Ash in the vicinity.
