Cochliomyia spp (New World Screwworm fly) are a parasitic blowfly which causes myiasis in cattle in the Americas.
C. macellaria is found throughout northern South America, Central America, Caribbean Islands, United States, and southern Canada. C. hominivorax has been eradicated from the U.S. and Mexico but still prevalent in South America.
Cattle are an intermediate host for this fly and secondary skin damage may result in lesions which can become infected.
