This photo is for a friend of mine Cindy/Little Acorns. It's a photo I took last December in Yucatan, Mexico, in a forest clearing, a shot I had not got round to uploading until now. Cindy, it is not a moth nor is it native to the British Isles, but I thought you might like to see it even so. It gets its name apparently through the fact that when flying the male is somehow able to crack its wings, which is believed to be the way it marks its territory and warns off other males, especially during the mating period. Personally until reading about this species I had no idea any butterfly could make a sound audible to humans. This one btw was about two inches from wing tip to wing tip
