This distinctive fly is sometimes called the Nest Skipper Fly. The larvae are parasites of birds, sucking the blood of nestlings. It has been found in nests of various birds, e.g. Greenfinches, Chaffinches, Linnets, Thrushes and Blackbirds. The name Skipper refers to the ability of the maggots to jump or skip several cm by bending then suddenly straightening. I found this specimen in my conservatory.
