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.
The subfamily Microdontinae contains slightly more than 400 species of hoverflies and, while diverse, these species share several characteristics by which they differ from other syrphids. The Microdontinae are myrmecophiles, meaning they live in the nests of ants. Larval Microdontinae are scavengers or predators in ant nests, and, in contrast to other syrphid larvae, have no readily apparent body segmentation. Some species also do not exhibit the typical adult flower-visiting behaviour of other hoverflies, but instead remain near their larval host colonies.
Hover flies of the genus Microdon are unusual among the Diptera. Like other members of the subfamily, they are myrmecophiles, meaning they inhabit the nests of ants.
Mallota is a widely distributed Holarctic genus of hoverfly, well known for their bee-like appearance.
Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.
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.
Eumerus is a genus of hoverflies, within the tribe Eumerini.
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.
Episyrphus is a genus of hoverflies in the subfamily Syrphinae. Larvae are predatory, often on aphids.
Chymophila is a subgenus of the hoverfly genus Microdon. It was previously considered to be exclusively Neotropical, but is now also known from the Nearctic and Oriental realms, and one species is known from Japan. Chymophila was based on a composite type species: the holotype is a body of C. fulgens with the head of a conopid glued on.
Pseudomicrodon is a genus of hoverflies, with 14 known species. All are species with petiolate abdomens.
Ocyptamus is a large and diverse genus of over 200 species of hoverfly mostly found in the Neotropical region. It is likely that many of these species will be discovered to be synonyms though many others await description.
Palpada is a genus of 85 neotropical and nearctic flower flies or hoverflies This genus is often colorful and bee-like. It is in the tribe Eristaliini containing dozens of genera Common sister genera include Eristalis (99 species), Meromacrus (43 sp.), Eristalinus (100 sp.) and Helophilus (50 sp.). The genus palpada is distinguished by:
Phytomia is a genus of at least 27 species of hoverfly from the family Syrphidae, in the order Diptera found in tropical Africa and Asia.
Graptomyza is a genus of hoverflies.
Sterphus is a genus of hoverflies.
Total of 245 species either found or highly expected to be found in New York.
