Otherwise, it was quite hard work finding any Lepidoptera despite the sunshine and nice habitats. 2 Narrow-bordered Five-spot Burnet and 3 Six-spot Burnet were pleasing, and a Marbled White was my first here since 1999 (though I haven't looked that often). An Ochsenheimeria vacculella swept from grassland was the 2nd Dingestow and 3rd Gwent record of this obscure Micro. Cydia nigricana were locally plentiful on Tares in one field, and the similar-looking Grapholita tenebrosana was beaten from a hedge. 3 more Stathmopoda pedella (from 2 different areas) suggest this species is having a good year.
The Longhorn Beetle Leiopus nebulosus was new for the site - the 16th species here.
