Feltiella
Feltiella is a genus of predatory gall midges (Cecidomyiidae) whose larvae feed on spider mites (Tetranychidae). The genus includes commercially important biological control agents, particularly F. acarisuga, which is mass-reared for augmentative biocontrol of tetranychid mites in greenhouse and agricultural systems. Larvae are voracious predators of spider mite eggs, with documented consumption rates exceeding 150 eggs per larva. Adults are short-lived and do not feed on prey.
