Cochliomyia hominivorax, commonly known as the human botfly, is a parasitic fly that primarily affects humans and other mammals. It is known for its larvae, which can infest the skin of their host, causing painful lesions. The adult fly is typically grayish in color and can be found in tropical and subtropical regions, particularly in Central America and South America. The life cycle of Cochliomyia hominivorax begins when the female lays eggs on the skin of a host. Once the eggs hatch, the larvae burrow into the skin, where they feed and grow. This species is of significant concern in veterinary and medical fields due to its potential to cause severe infections and complications in affected individuals.
