I Spy With My Little Eye

Can you spy what I spied here?



As many will know, not a subject I particularly like to get near:



But fascination got the better of me:



What was most interesting to me was the pale marking on each wing. In the photos it tends to look yellow but actually seemed to glitter like gold leaf. In spite of the gold colour this appears to me to be a Silver Y (Autographa gamma) moth. With a wing span of 30 - 45mm I definitely do not want to see any of these indoors.
