Eristalis is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies because they bear a resemblance to honeybee drones.
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.
Dasysyrphus is a genus of hover flies with 50 identified species distributed worldwide. While the genus is relatively easy to identify, the differences between species have a more narrow range of variations. Therefore, identification of species by images of specimens alone should be made with care.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Chalcosyrphus is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus Xylota but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic feeders in rotten wood in these habitats.
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.
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.
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 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.
Anasimyia is a genus of wetland hoverflies with aquatic larvae. The genus was formerly regarded as a subgenus of the similar Lejops, and recently elevated to genus.
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.
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.
Orthonevra pictipennis (Loew,1863), the Dusky-veined Mucksucker, is an uncommon species of syrphid fly. It has been observed in North America. O. pictipennis shares much of the same range as O. pulchella, O. nitida and O. feei. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies, for they are commonly found around and on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. O. pictipennis larvae have not been described.
Lejota is a genus of syrphid flies in the family Syrphidae.
The Brachyopina is a subtribe of hoverflies.
Total of 245 species either found or highly expected to be found in New York.
