Anu is a genus of hoverfly, from the family Syrphidae, in the order Diptera. It is only known from New Zealand. [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.
Melangyna viridiceps is an Australian hoverfly, known as the common hover fly.
Helophilus are a diverse genus of moderate to large hoverflies, that appear somewhat bee-like. Larvae filter-feed in organic rich water. All Helophilus adults have a distinctive lengthwise striped thorax and a transverse striped abdomen.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Aristosyrphus is a genus of Neotropical hoverflies.
Ceratophya is a genus of hoverflies, with five known species. They are distinct from Microdon by the presence of an appendix on vein R4+5. Many species have erroneously been placed in this genus. Some authors place Ceratophya as a subgenus of Microdon.
Megodon is a subgenus of the hoverfly genus Microdon. It is native to Madagascar, and contains only two known species. Microdon stuckenbergi has an unusual scutellum. Larvae are found in ant nests.
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.
Paragodon paragoides is a small (4–5 mm) hoverfly which differs from other hoverflies by its simple male genitalia, and was accordingly considered the most primitive microdontine species. It is the sole member of the genus Paragodon, as the other known species was removed to a separate genus, Surimyia.
Paramicrodon is a genus of hoverflies, with eight known species. They differ from Microdon by their short antennae and the lack of appendices on vein R4+5.
Parocyptamus is a genus of hoverflies, with two known species. The critical characteristic is the narrow, elongated abdomen.
Ptilobactrum is a genus of hoverflies, with one known species, Ptilobactrum neavei. They have very broad heads and their basoflagellomeres are elongate and densely pilose in males.
Rhoga is a genus of hoverflies, with five known species. All are small, delicate, pale yellowish flies, with distinct black pilose brushes on their metatibiae. These flies are probably mimics of stingless bees of the tribe Meliponini.
Rhopalosyrphus is a genus of hoverflies, with nine known species. The adults flies mimic wasps, such as Zethus. The larvae are predators of ant brood. They are native to from southern United States to northern Argentina.
Schizoceratomyia is a genus of hoverflies, with four known species. Larvae are found in ant nests. They are native to the Neotropics.
Ubristes is a genus of hoverflies, with four known species. All are characterized by their metatibiae, which are usually enlarged, but always with a brush of long pile along the dorsal edges. These flies are probably mimics of the stingless bees in the tribe Meliponini.
Surimyia is a genus of hoverflies, with three known species. They are small microdontine flies. Surimyia is the only hoverfly genus with the katatergum lacking microtrichia. In the subfamily Microdontinae, they are distinctive in the absence of pilosity on the postpronotum.
Helophilus seelandicus, commonly known as the three-lined hoverfly, is a hoverfly endemic to New Zealand. The common name corresponds to the three black lines behind the insect's head.
