Ephydridae
Ephydridae (shore fly, sometimes brine fly) is a family of insects in the order Diptera. Shore flies are tiny flies that can be found near seashores or at smaller inland waters, such as ponds. About 2,000 species have been described worldwide, including Ochthera. The petroleum fly, ''Helaeomyia petrolei'', is the only known insect whose larvae live in naturally occurring crude petroleum. Another notable species is ''Ephydra hians'' which lives in vast number at Mono Lake. Description For terms, see Morphology of Diptera. The flies are minute to small (0.9 to 7.0 mm), with black or gray colorations. Wings are sometimes patterned. Costa with two interruptions are present in first section, near the humeral cross-vein and again near the end of vein 1. The second basal cell is not separated from the discal cell. Arista are bare or with hairs on the upper side (plumose on the upper side). The mouth opening is very large in some species. The ratio of vertical diameter of e ...
