This one's got me completely foxed. It's sitting on our front room window right now (been there all day) and I just can't identify it. It's only a little over 2cm from wingtip to wingtip.
I've asked Moonlight to look through his Aunt Priscilla's moth books when he goes down there to look after her farm animals, but I think he's going to be too busy trying to keep away from her geese
Edit: just been told by a Facebook friend that it's a Common Marbled Carpet
