Definition & Meaning of "human botfly"

What is a "human botfly"?

A human botfly is a parasitic insect that infests humans and other mammals. The adult female botfly lays eggs on mosquitoes or other biting insects, which then transmit the eggs to a host when they bite. The eggs hatch into larvae that burrow into the host's skin, causing painful and itchy lesions. The botfly larvae develop within the host's tissue until they eventually emerge as fully-grown flies. Human botfly infestations are typically found in tropical regions and can be treated by removing the larvae surgically or through natural means.
