About Blow Fly

Blow flies are a diverse group ranging from 6 to 14 mm in length and generally having a metallic sheen to their bodies. The black blow fly has a dark, olive-green body, black legs, and orange pubescence around the mesothoracic spiracles. The secondary screwworm fly also has a green body, but its head is predominantly orange. The body of the green-bottle fly, Phaenicia sericata, is primarily a coppery green with yellowish mouthparts. Lucilia cuprina is a medium sized fly and is mostly a bronze color. All blow flies have blunt mouthparts and do not bite.

Feeding

Most blow fly larvae feed in carrion or other decaying organic matter. They often infest wounds of sheep, goats, cattle, and other animals. Unkempt sheep are particularly subject to attack. Adult blow flies are attracted to nectar, carrion, garbage, and other refuse and soggy, bloody or soiled hair, fur, or wool.
