Brachydeutera
Brachydeutera is a genus of shore flies in the family Ephydridae, containing approximately 16 described species. Members of this genus are characterized by their association with aquatic or semi-aquatic habitats, where they occupy the hyponeustic zone—living just below the water surface. The genus was established by Loew in 1860 and has been documented across various regions with observations spanning multiple continents.
Brachydeutera sturtevanti
Brachydeutera sturtevanti is a species of shore fly in the family Ephydridae, first described by Wirth in 1964. It is characterized as a hyponeustic generalist, meaning it inhabits the water surface film of aquatic or semi-aquatic environments. The species has been documented in the immature stages, with larvae adapted to life at the air-water interface.
