The tarsi (last 5 segments of the hind leg) is the key to identifying the Sphaerocerid fly. On this particular fly, the first segment of the tarsi is greatly enlarged. Sphaerocerid Fly Biology and Life History The Sphaerocerid fly belongs to a large family of flies known as Sphaeroceridae which contains 241 species in North America. Most flies of

Soldier flies are large, rather stocky, 3/8 to 1/2 inch long.
