Eristalinae are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, Eristalis tenax.
Myathropa florea, sometimes referred to as the Batman hoverfly, is a very common European and North African species of hoverfly. Adults may be seen on flowers from May to September. It is of a similar size to the common drone fly, but Myathropa are generally more yellow, with two light bands to the thorax, interrupted with a black central smudge. In museum specimens, any yellow colour soon fades to brown after death. Like most species in the tribe Eristalini, Myathropa are rather variable in size, shape and colour.
Spilomyia is a genus of hoverflies. Many species in the genus show Batesian mimicry of wasp models, including black and yellow patterns and modified antenna shape.
Dasysyrphus is a genus of hover flies with 50 identified species distributed worldwide. While the genus is relatively easy to identify, genera key 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.
Dasysyrphus albostriatus is a Palearctic species of hoverfly.
Dasysyrphus venustus is a Holarctic species of hoverfly.
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.
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.
The Syrphini are a tribe of hoverflies.
Dasysyrphus friuliensis is a European species of hoverfly.
Dasysyrphus pauxillus is a North American and European species of hoverfly.
Dasysyrphus osburni is a species of syrphid fly in the family Syrphidae. It is found in Europe.
'Dasysyrphus intrudens' is a placeholder name for a complex of hover fly species that have yet to be properly been divided into individual species. It is found in the Holarctic realm. Though this species actually a complex, it is commonly found in many areas of its range, but yet the larvae of this species were not known to science as of 2012. This may be due to the probable nocturnal habit of these larvae if it is similar to some known larvae of this genus.
Nepenthosyrphus is a genus of hoverflies in the subfamily Eristalinae.
Nepenthosyrphus venustus is a species of hoverfly in the family Syrphidae.
Total of 245 species either found or highly expected to be found in New York.
