Forcipomyia genualis
Loew, 1866
Forcipomyia genualis is a of biting midge in the Ceratopogonidae. Like other members of the Forcipomyia, are minute flies, typically 1–3 mm in length. The genus includes species with diverse feeding habits: some females bite birds or mammals, others feed on the blood of large insects such as and , and some are . Larvae develop in moist or decaying organic substrates, feeding on , plant debris, or fungi.

Identification
Identification to level requires examination of male genitalia and other microscopic features. Members of Forcipomyia can be distinguished from other ceratopogonid by characteristics of the wing venation, antennal structure, and palpal segments. Males possess (feather-like) with long setae, which function in detecting female wingbeat frequencies. Females have shorter, less hairy antennae.
Habitat
Larvae inhabit moist or decaying organic matter, including compost, leaf litter, soil, and substrates with or fungi. are found in humid environments near larval development sites.
Distribution
Recorded from the Galápagos Islands and several states in Brazil (Amazonas, Bahia, Rio de Janeiro, Santa Catarina).
Behavior
males form aerial swarms over landmarks to attract females. Mating typically occurs in . Both sexes feed on nectar and other sugary liquids for energy.
Ecological Role
Larvae contribute to decomposition of organic matter. Some Forcipomyia are of plants, including cacao (Theobroma cacao), though the specific role of F. genualis in pollination has not been documented. may serve as prey for other insects.
