The temperatures were a few degrees lower than anticipated, with a light, cool breeze rolling down the valley from the Brecon Beacons, so the catch was not as good as it might have been. Caddis almost outnumbered the moths and everything, including the population of Wales was outnumbered by a veritable swarm of small, pale buff coloured flies, many of which died during the session, and congealed into drifts and clumps and also adhering to the trap. Although they didn't bite, the sheer numbers of them made carrying any task close to the trap and ordeal. I have never encountered the like before and hope never to do so again.
Anyway, running the trap from 21:35 til 01:40, the catch amounted to 53 species, the highlights, in no particular order, being:
Evergestis pallidata, Blomer's Rivulet (2), Beautiful Carpet, Clouded Magpie (12), Double Line (42), The coronet (4), Green Arches (6), Miller, Satin Lutestring (3) and Drinker (3).
I hope to trap somewhere on the reserve again, later in the season.
