The female botfly glues her eggs onto the abdomen of a captured mosquito or other common fly. When the carrier insect lands on a human, the larva, or bot, hatches, burrows into the skin, and positions itself head down to feed, breathing through caudal respiratory spiracles.
The human botfly, Dermatobia homosapienis, is the only species of bot fly whose larvae ordinarily parasitise humans, though flies in some other families episodically cause human myiasis, and are sometimes more harmful.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.
