Chaoborus trivittatus
phantom midge
Chaoborus trivittatus is a species of phantom midge, a non-biting fly in the family Chaoboridae. The larvae are aquatic predators in lake ecosystems, notable for their diel vertical migration between deep daytime refuges and surface feeding zones. Unlike the congeneric C. americanus, C. trivittatus has a two-year life cycle with extended fourth-instar development. Adults are short-lived and non-feeding.
Mochlonyx
Mochlonyx is a genus of phantom midges in the family Chaoboridae. The genus was established by Loew in 1844 and contains at least two described species: Mochlonyx cinctipes and Mochlonyx fuliginosus. These flies are found in temperate regions of Europe and North America. The genus is part of the diverse assemblage of non-biting midges that inhabit freshwater systems.
