Red-letter Flat-bodyAgonopterix ocellana
Red-letter Flat-body is closely related to the Black-spot Flat-body, but the two species can be told apart easily. Especially the red scales in the wing of Red-letter Flat-body do make it stand out. The amount of them varies per specimen though. Reaching a wingspan of 19 to 22 mm the Red-letter Flat-body is quite a small species. It is on the wing mainly from September to May, so the adults overwinter. Yet there might be a summer generation flying about as well. The larvae live on various species of Willows. The Red-letter Flat-body is relatively common in Britain, rather common in Belgium and common in the Netherlands.
