Hadromyia is a genus of hoverflies in the family Syrphidae. There are about seven described species in Hadromyia. [3]
Subgenus Chrysosomidia Curran, 1934 [2]
Subgenus Hadromyia (Williston, 1882) [1]
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.
Cylindromyia is a genus of flies in the family Tachinidae.
Peleteria is a widespread genus of flies in the family Tachinidae.
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
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.
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.
Mixogaster is a genus of hoverflies native to North America and South America, with 21 known species. Mixogaster is distinct by lacking an appendix on vein R4+5, having a reduced and bare metasternum, an unarmed scutellum, and usually an appendix on vein M extending in cell R4+5. Larvae are found in ant nests.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
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.
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.
Cynorhinella is a genus of hoverflies from the family Syrphidae, in the order Diptera. Curran erected Cynorhinella for a new species which he named canadensis. He states in the description: "I am unable to place the following specimen in any genus known to me, and it traces out to Cynorhina in Williston's manual, and apparently comes closest to this genus but the thickened, arcuate hind femora with the projection apically, and the more distinct facial side margins separate it. It is related to Chilosia and Chrysochlamys by the last mentioned character, but there is no semblance of bristles and the shape of the abdomen is distinctive."
Sterphus is a genus of hoverflies.
Total of 245 species either found or highly expected to be found in New York.
