Frit fly

Definition

Any small fly of the family Chloropidae (order Diptera), characterized by a shiny, nearly hairless body that is typically yellow or black. The larvae of most species are phytophagous, feeding primarily on grasses and cereal crops, where they can reach pest status; some species are parasitic, predatory, or kleptoparasitic.

Etymology

From 'frit,' a dialect term for cereal grains (especially barley), referring to the group's association with grass and crop pests.

Example

The frit fly Oscinella frit is a significant pest of oats and barley in Europe, with larvae mining within the central shoots of young plants.

Synonyms

• grass fly

Related Terms

Usage Notes

Often used interchangeably with 'grass fly' for the family Chloropidae, though 'frit fly' emphasizes the agricultural pest species. Not to be confused with 'eye gnats' (Hippelates, Siphunculina), which are medically significant members of the same family attracted to lachrymal secretions.
