Pyrausta nigrata at Caerwent
I visited MoD Caerwent today with Martin and Roger. Plenty of nice butterflies and moths including Drab Looper and Grizzled Skipper in reasonable numbers (though undoubtedly still to peak), plus a few Dingy Skipper and a single Brown Argus. Most exciting for all three of us, though, was the handsome micro-moth Pyrausta nigrata. We saw 3 of these in a small area of grassland, exactly where Martin and Sam B had seen them back in 2004. Caerwent is the only known site for this species in Gwent, and it is very rare in Wales generally.
