An Annotated List of Genotypes of the Chloropidae of the World (Diptera)

The family Chloropidae is composed of small flies (Diptera), averaging about 2 mm. in length, which are often collected in great numbers in studies of grain and pasture grass insects and in sweeping grass and low vegetation. The European frit fly, the gout fly of barley, the wheat stem maggot, the eye fly of India and the East Indies ( Siphunculina funicola ), the eye gnats ( Hippelates spp.), and Pseudogaurax signatus , an egg predator of the black widow spider, are among the better known species. The eye gnats ( Hippelates ) are an important group because of the tremendous number of individuals, their persistently annoying habits, and their relation to the transmission of yaws and several epidemic eye diseases.
