- A genus of botflies whose larvae are the cause of a tropical form of myiasis linearis (cutaneous larva migrans) of man; occasionally they invade the interior of the eye. Two species, H. bovis and H. lineatum, are botflies of cattle. The ova of H. 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]
* * *hy·po·der·ma .hī-pə-'dər-mə n1) cap a cosmopolitan genus (the type of the family Hypodermatidae) of dipteran flies that have larvae parasitic in the tissues of vertebrates and include the heel flies and the common cattle grub (H. lineatum)2) any insect or maggot of the genus Hypoderma
* * *n.a genus of non-bloodsucking beelike insects - the warble flies - widely distributed in Europe, North America, and Asia. Cattle are the usual hosts for the parasitic maggots, but rare and accidental infections of humans have occurred (see myiasis), especially in farm workers. The maggots migrate beneath the skin surface, producing an inflamed linear lesion similar to that of creeping eruption.
* * *Hy·po·der·ma (hi″po-durґmə) [hypo- + Gr. derma skin] the ox-warble flies or heel flies, a genus of insects of the family Oestridae whose larvae cause larva migrans in humans and warbles in cattle.
