Found in the light trap in a South Wales urban garden. Sorry about the poor photo, but it refused to settle for a decent photo. Struggling with this one, would appreciate any corrections.
About 2cm. Dark pattern, with a light spot on each wing. The guide says it appears from late June, so is it too early for a Dot?
