: any of various small dipteran flies (as a drosophila) whose larvae feed on fruit or decaying vegetable matter
Fruit fly (Trypetidae)—E.S. Ross
Any dipteran species of two families: large fruit flies (Trypetidae) and small fruit flies, or vinegar flies (Drosophilidae; seedrosophila). The larvae feed on fruit or other vegetation. The adults' wings are banded or spotted with brown. Many species attack cultivated fruits, sometimes causing enough damage to create significant economic loss. Some species are leaf miners; others burrow in plant stems. Well-known fruit-fly pests include the Mediterranean fruit fly and the apple maggot of the U.S., the Mexican and Oriental fruit flies, and the olive fruit fly of the Mediterranean region.
