Leptoconops (black gnat)[1] is a midge genus in the family Ceratopogonidae.[2] It has a mostly tropical or subtropical distribution worldwide,[3] but some species occur as far north as Moscow region in Russia and the Yukon Territory in Canada.[4]

This genus is relictual, having had a pantropical distribution during the Cretaceous.[5] The presence of Leptoconops, along with Austroconops, in ancient Lebanese amber makes these the earliest existing lineages of biting midges.[3] Extinct species have also been described from amber from Siberia, New Jersey, Canada, Hungary, Sakhalin, France,[4] and Spain.[6]

Adult Leptoconops females are diurnal feeders, and suck vertebrate blood. Adults of both sexes in some species rest by burying themselves in sand.[7] Larvae feed on algae, fungi, and bacteria. They burrow in moist, usually saline, sand or mud of desert areas and coastal and inland beaches.[3][4]
