After surveys in the Alun Valley today, I had a bit of a poke around for moths on the steep stony slopes near the St Bride's Road. I found two interesting plumes, Merrifieldia leucodactyla and the tiny but rather lovely Oxyptilus parvidactylus. On checking MapMate, I see there are only two previous VC41 records of the latter, but both from the same site.
Other species seen included Small Purple-barred, Chalk Carpet and this strange little micro which is one of the Ochsenheimeria species - I'm not sure which one though! There are a few county records of taurella but none of urella, so I guess I should hang on to it.
