The coxcomb prominent is chestnut in colour with variable patterns, and creamy tufts of hair on the body. It has a distinct profile when at rest, which resembled a cock's comb. This individual is slightly damaged so the profile is a little off. Two broods are produced every year, both overwintering as pupae. They emerge in May and June (first brood) and then again in August and September (second brood). This is an early emergent of the second brood!
Very common throughout Europe, larvae feed on deciduous trees
I found this guy on the stairs at the university, I think he's badly hurt because these moths fly at night.
