Family: Drosophilidae, Pomace Flies view all from this family



Description A slender fly. Adult males bright golden-yellow, covered with dense upright hair, orange-yellow hair on front legs. Females duller in color with shorter hair with pronounced green-brown tinges, and lack bright coloured fur on the fore legs. Long, hair-covered; eyes red; wings yellowish brown in front, clear behind.


Dimensions Adult preys on flies and other adult insects. Larva feeds on other insect larvae in dung.


Food Adult preys on flies and other adult insects. Larva feeds on other insect larvae in dung.


Life Cycle Females lay their eggs on manure. The eggs hatch into predatory larvae and feed on other insect larvae within the dung. After 21 days or more of feeding, dependent on conditions, the larvae burrow into the soil around and beneath the dung and then develop into pupae, before developing into adult flies. Up to four or five generations per season.


Habitat Locations with manure present such as Barnyards and pastures.


Range Introduced. Found throughout the United States and southern Canada.


Discussion One of the most familiar and abundant of flies in many parts of the northern hemisphere. It is a very variable in appearance, which research is hinting may be driven in part by climate variations. European colonists inadvertently brought the dungfly to the New World with their livestock.
