Brachyopini

Chrysogaster is a genus of small hoverflies in the subfamily Eristalinae. They are dark or black with shiny colourful reflections and can often be seen visiting flowers in damp marshy areas where the aquatic larvae live. Species in the related genera Melanogaster, Orthonevra, Lejogaster and Riponnensia were formerly treated as members of Chrysogaster.

Orthonevra is a genus of flies in the family Syrphidae. They are worldwide in distribution with at least 59 species identified concentrated mainly in eastern North America and Europe. Species of the genus Orthonevra are commonly called mucksuckers after the larvae which have been found in organic rich mud, i.e. muck. This genus belongs to the tribe Brachyopini that includes the prominent genera Melanogaster, Brachyopa, Neoascia and Sphegina.

Brachyopa is a Holarctic genus of hoverflies whose grey and brown colouration is unusual for this family and these flies can easily be overlooked amongst members of other fly families. The larvae can be found under the bark of dead branches and trees in decaying sap.

Sphegina is a genus of small, slender hoverflies. They are widespread throughout Eurasia and North America. In flight they seem to have long hind legs which they often carry hanging down, making them resemble sphecid or ichneumonid wasps. Adult Sphegina are usually found in damp and shady habitats close to water in forested areas, and several species can often be found together. They often feed on white and yellow flowers of Apiaceae, Ranunculaceae, Asteraceae, and Rosaceae like Crataegus, Sorbus, and Sorbaria. Larvae nest in the sap of living and dead trees or in decaying cambium under tree b

Neoascia is a genus of small black and yellow or mostly black flies with a narrow abdomen near the thorax. They occur mainly in damp places among low herbage. The larva of Neoascia are flattened without oral hooks and a have a short posterior spiracular process or "tail", and are saprophagous. In 1925 Curran reviewed the genus Neoascia . In this work a key is provided and ten species are described including four new species some of which have later been determined to be synonyms.

Hammerschmidtia is a Holarctic genus of hoverflies whose larvae live in sap under the bark of freshly fallen trees. ==Diagnostics== For terminology see Speight key to genera and glossary The face of the male is tuberculate, with long hairs on the upper and lower sides of the lower three-quarters of the arista. Most of the hairs are several times longer than the arista. The scutum is armed with very evident spines, while the anepisternum, postalar callus, and scutellum have strong bristles. The abdomen is twice as long as the thorax, and the first posterior cell does not end acutely from the a
