This moth flew in last night, attracted to light. Working through my guide I came to the conclusion it was a Hedge Rustic (Tholera cespitis), as it was a perfect match for size, shape and flying time - however looking at my picture and comparing it to others on the internet I'm not sure any more!!
I've only been looking at moths for a couple of months, so would appreciate some more experienced opinions!!
