The human botfly, Dermatobia hominis, (Greek δέρμα, skin + βίος, life, and Latin hominis, of a human) is one of several species of fly, the larvae of which parasitise humans (in addition to a wide range of other animals, including other primates). It is also known as the torsalo or American warble fly, even though the warble fly is in the genus Hypoderma and not Dermatobia and is a parasite on cattle and deer instead of humans.
