I got the rare chance to do some moth trapping at Pembrey Sands Air Weapons Range this week, as Butterfly Conservation Wales had secured some funding from the MOD to do survey work at the site. For those of you who don't know it, this is a really interesting site ecologically-speaking, with sand dunes, wet grassland, saltmarsh and scrub woodland.
Along with Dai Rees we set up five traps (two MV, one Actinic and two portable LED) around the western end of the site. It wasn't exactly a warm night, and with a nagging breeze we needed several layers to keep warm. Nevertheless the moths trickled in, with a few species of interest including Cream-bordered Green-pea and Grass Eggar. Just before midnight the wind suddenly died away to nothing, and the moths really started to come in numbers. But it's a long drive home from the end of the Pembrey peninsula, so we reluctantly packed up just before 1am with an excellent total of 98 species recorded.
As well as the macro-moths mentioned above, some uncommon or localised micros were recorded including Agonopterix kaekeritziana, several Hoary Plume (Platyptilia isodactyla), Notocelia incarnatana and Hedya ochroleucana.
It's certainly a site that would warrant more trapping effort across the season, as Ian tells me that little trapping has been done there.
