Introduction (Back to Top) The human bot fly, Dermatobia hominis (Linnaeus Jr., 1781), is a large, densely haired fly that looks like a bumblebee (Kahn 1999). The human bot fly is native to Central and South America. The fly is not known to transmit disease-causing pathogens, but the larvae of D. hominis will infest the skin of mammals and live out the larval stage in the subcutaneous layer, causing painful pustules that secrete fluids.
Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. The human botfly, Dermatobia hominis, is the only species of bot fly known to parasitize humans routinely, though other species of fly do cause myiasis in humans.otflies deposit eggs on a host, or sometimes use an intermediate vector such as the common housefly, mosquitoes, and, in the case of Dermatobia hominis, a species of tick. The smaller fly is firmly held by the botfly female and rotated to a position where the botfly attaches some 30 eggs to the body under the wings.
