The 3rd antennal joint is compressed, as long as the first and 2nd taken together, and near the base at the back has a long arista, which is much longer than the antenna itself. The proboscis is much longer, nearly 1/3 of the height of the head, the oral opening is oval andnarrower towards the apex. The vertex (female) is much narrower than the half breadth of the front between the antennae. The compound eyes are pubescented. The wings are broader and longer, the 3rd longitudinal vein opens before the apex and is nearly straight or a little curved. The ...

Syrphini
The Syrphini are a tribe of hoverflies. List of genera Relationships within this tribe were investigated by analysing and comparing genetic data. Results seem to show the members of Syrphini fall into several smaller groups or clades. *''Afrosyrphus'' Curran, 1927 *'' Agnisyrphus'' Ghorpade, 1994 *'' Allobacha'' Curran, 1928 *'' Allograpta'' Osten Sacken, 1875.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Syrphinae
The Syrphinae constitute one of the three subfamilies of the fly family Syrphidae. Most larvae of this subfamily feed on aphids. It is a monophyletic group with more than 1,600 species.
