Senaspis is a genus of 14 species of Afrotropical hoverfly from the family Syrphidae, in the order Diptera. [1]
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.
Syritta is a genus of hoverflies, family Syrphidae.
Eumerus is a genus of hoverflies, within the tribe Eumerini.
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.
Melangyna is a genus of hoverflies.
Blera is primarily a North American genus, though there are 3 species from Europe. The genus is characterized by the following characters:
Austalis is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
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.
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.
Asarkina is a genus of hoverfly.
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.
Orthoprosopa is a genus of hoverflies from the family Syrphidae, in the order Diptera.
Total of 245 species either found or highly expected to be found in New York.
