The Rhingiini (or Cheilosiini) is a tribe of hoverflies.
Paragus is a genus of hoverflies.
Merodon is a large genus of bee-like hoverflies. The majority of the species are centered on the Mediterranean and it is the second largest hoverfly genus in Europe with more than 50 European species. It is distributed over the Palaearctic and Afrotropical realms, with most European species occurring in Southern and Eastern Europe. The centre of distribution of this genus appears to be Turkey, where about 65 species have been recorded. Some species occur in Africa and the middle East, as far as Pakistan. Given the rate at which new species have been recorded over the past decades, the worldwide number of species could exceed 200. The larvae feed on the bulbs or rhizomes of monocotyledons.
Cheilosia is a genus of hoverfly. Most Cheilosia are black or largely un-coloured, lacking the bright colours and patterns of many hoverfly species. It is one of the most species diverse genera of hoverflies. The biology of many species is little understood, but where known, the larvae of Cheilosia species feed in the stems of plants or in fungi.
Eumerus is a genus of hoverflies, within the tribe Eumerini.
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.
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 bark lying in water or other damp conditions. The larvae of some species have been discovered in the tunnels of other xylophagous insects.
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.
These are 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 Neosascia are flattened without oral hooks and a have a short posterior spiracular process or "tail" rat-tailed that is 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.
Orthonevra is a genus of fly in the syrphidae family with at least 59 species identified so far. They are worldwide in distribution but concentrated in the Eastern North America and Europe.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. Orthonevra have black heads with blue to purple reflections. Many species have distinctive eye stripes. The antennae are somewhat elongate. The frons is wrinkled with silvery spots at sides of antennae. The thorax with small punctures dorsally and in several species the body is covered with scale-like pile. Wingd vein M1 curves away from the wing tip.(see images)
Psilota is a genus of small black hoverflies with long wings, from the family Syrphidae, in the order Diptera. They are one of the few hoverfly genera that do not have a venia spuria in the wings. The larvae feed on tree sap.
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
Pipizella is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Trichopsomyia is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Brachypalpus is a genus of hoverflies, from the family Syrphidae, in the order Diptera. The head is triangular and produced well forwards and somewhat downwards. The thorax and abdomen with pile often rather long. The hind femur is swollen and with an obtuse spur apically and ventrally. The hind trochanters of male is spurred.
The larvae are of the rat-tailed type feeding on decaying sap under tree bark. Larvae live in decaying trees and logs. Larva and pupa have been described by Malloch.
The Brachyopini is a tribe of hoverflies. Unlike many members of this family these flies are generally darker and less colourful though some genera contain species with an attractive metallic lustre e.g. Chrysogaster. Some like Brachyopa are associated with sap runs where their larvae feed on decaying sap. Others are found in boggy areas where their often semiaquatic larvae feed on decaying organic matter.
The Eumerini is a tribe of hoverflies. The breeding habits of this group varies: larvae of the genera Merodon and Eumerus tunnel into plant bulbs while larvae of Psilota have been found in sap runs.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
Xylota abiens is a European species of hoverfly.
The Brachyopina is a subtribe of hoverflies.
Brachyopa minima is a European species of hoverfly.
