A genus of nonbloodsucking 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 man have occurred, especially in farm workers. The maggots migrate beneath the skin surface producing an inflamed linear lesion similar to that of creeping eruption.
A genus of warble flies of the family Oestridae. The larvae of some species attack cattle and, rarely, humans. They cause a subcutaneous channel of inflammation as they burrow under the skin.
