Adults, 6 mm long with a wingspan of 13-15mm and the 4th vein on the wing bends sharply forward. The thorax has 4 distinct stripes.

Biology:
The eggs are laid in decaying material, particularly rubbish dumps and manure heaps. Under ideal conditions it can take as little as 2 weeks to complete its life cycle.

Control:
Removal and exclusion of breeding sites, such as refuse areas, is essential. Space sprays with a knockdown action are a good method of control and again proofing of doors and windows. Unlike the Lesser House Fly, electric fly killers can be effective at killing these flies when they enter premises.
