Cochliomyia
Cochliomyia is a genus in the family Calliphoridae, known as blowflies, in the order Diptera. Cochliomyia is commonly referred to as the New World screwworm fly. The four species in this genus are: C. macellaria, C. hominivorax, C. aldrichi, and C. minima.C. hominivorax is known as the primary screwworm because its larvae produce myiasis and feed on living tissue. This feeding causes deep, pocket-like lesions in the skin, which can be very damaging to the animal host. C. macellaria is known as the secondary screwworm because its larvae produce myiasis, but feed only on necrotic tissue. This species is forensically important because it is often associated with dead bodies and carcasses. Both C. hominivorax and C. macellaria thrive in warm, tropical areas.
