Just back from a week of studying Moths and Butterflies in the Highlands at Kindrogan Field Studies Centre. About 20 new species for me. Mostly the ones flying at this time of the year are fairly cryptic but close examination reveals the fantastic designs.  

The one on the left is Golden-rod Brindle a local species that can be found by cold searching posts during the day. You can easily see the problem a bird would have in trying to decide if it was wood or food.
