Screwworms
''Cochliomyia'' is a genus in the family Calliphoridae, known as blow-fly, blowflies, in the order Diptera. ''Cochliomyia'' is commonly referred to as the New World screwworm flies, as distinct from Chrysomya, Old World screwworm flies. Four species are in this genus: ''Cochliomyia macellaria, C. macellaria'', ''Cochliomyia hominivorax, 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 Necrosis, necrotic tissue. Both ''C. hominivorax'' and ''C. macellaria'' thrive in warm, tropical areas. Characteristics Adult In general, all Diptera have three body regions (head, thorax, and abdomen), three pairs of legs, one pair of forewings used for flight, one ...

Cochliomyia Macellaria
''Cochliomyia macellaria'', also known as the secondary screwworm, is a species of Calliphoridae, blow fly in the family Calliphoridae. These screwworms are referred to as "secondary" because they typically infest wounds after invasion by primary myiasis-causing flies. While Calliphoridae, blow flies may be found in every terrestrial habitat, ''C. macellaria'' is primarily found in the United States, American tropics, and sometimes southern Canada. They are most common in the southeastern United States in states like Florida. ''C. macellaria'' have a metallic color, metallic greenish-blue thorax and a red-orange head and eyes. These adult blowflies range from 5–8 mm in size. Since the fly Larva, larvae infect the wounds and dead tissue of animals, these flies pose a grave medical and economic risk to humans and livestock. ''C. macellaria'' are attracted to carrion and garbage and are often found in slaughterhouses and outdoor markets in the tropics. While these flies ca ...
