Pronunciation: hi'po-der'ma

Definition: A genus of botflies the larvae of which cause a tropic form of myiasis linearis (cutaneous larva migrans) in humans; occasionally they invade the interior of the eye. Two species, Hypoderma bovis and Hypoderma lineatum, are botflies of cattle. The ova of Hypoderma bovis are deposited on hairs of the legs, and the larvae penetrate the skin and migrate through the tissues to the skin of the back, where they appear during late winter as the common warbles; these ulcerate to the surface and mature larvae escape in early summer, fall to the ground, pupate, and give rise to a new generation of flies.

[hypo- + G. derma, skin]
