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.
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.
Volucella bombylans is a large species of hoverfly belonging to the family Syrphidae.
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.
Temnostoma is a genus of hoverflies. The larvae of some species feed on the wood of deciduous trees.
The genus Chrysotoxum consists of large, wasp-mimicking species. The adults are distinguished by very long antennae, oval abdomen with yellow stripes, and yellow patterns on the thoracic pleurae . The species of Chrysotoxum are chiefly Holarctic in distribution. . The species in this genus, are mostly very uniform in structure and colour and are separated with difficulty. Larvae are specialized in preying upon root aphids associated with ant nests.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Criorhina is a genus of hoverflies. Medium to large sized species, black or greenish black, with or without light ground markings mimicking bumblebees. The head is much flattened and broader than the thorax. The antennae are situated upon a prominent conical frontal process, The face is moderately produced below the eyes, downward or forward, in profile. The eyes are bare. The abdomen is elliptical or very short oval. Larvae found in rot holes or decaying hardwoods
Myopa is a genus of flies from the family Conopidae.
Blera is primarily a North American genus, though there are 3 species from Europe. The genus is characterized by the following characters:
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.
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.
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
Trichopsomyia is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Milesia is a genus of very large hoverflies, which mimic social wasps. For example, the European species Milesia crabroniformis is a convincing mimic of the hornet species Vespa crabro. Milesia are predominantly Palaeotropical in distribution almost entirely Oriental.
Hermetia is a genus of flies of the family Stratiomyidae.
Total of 245 species either found or highly expected to be found in New York.
