White-spotted Pinion Cosmia diffinis

The rarest and most attractive of the four british Cosmia species, this moth underwent a rapid decline as a result of Dutch elm disease during the 1970s. The moth is now scarcely distributed in parts of southern England. The flight period is from July to September, and the species is attracted to light. Image: Will George (Flickr).
