Adult cluster flies are just a little larger than a common house fly. They are dull-gray with black markings and have golden-yellow hairs on the thorax, which give the appearance of a golden sheen.

The immature stages, egg and larva, are seldom seen as the eggs are deposited on the soil and the larva or maggots burrow into earthworms on which they feed. The maggots are cream colored and are an elongated wedge shape. Also a member of the fly family Calliphoridae. Usually Cluster flies will come out from cracks under or behind baseboards, around window and door trim, and around exhaust fans or lights in ceilings. Home owners should seal openings with caulk or other suitable materials to prevent the insects from crawling out.
