Metadon is a genus of hoverfly containing 43 species. Most of the species were originally described in the genus Microdon . [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.
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.
Eumerus is a genus of hoverflies, within the tribe Eumerini.
Temnostoma is a genus of hoverflies. The larvae of some species feed on the wood of deciduous trees.
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.
Archimicrodon is a genus of hoverflies. Many of the species in this genus were moved from Microdon by Reemer & Ståhls (2013). Previously, it had been described as having three known species.
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.
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.
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.
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.
Paramixogaster is a genus of hoverflies, with 25 known species. Paramixogaster has an appendix on vein R4+5 that is absent in Mixogaster.
Pseudomicrodon is a genus of hoverflies, with 14 known species. All are species with petiolate abdomens.
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.
Spheginobaccha is a genus of hoverflies, with 15 known species. The genus is readily separated from other microdons by the incomplete metathoracic bridge, round/oval basoflagellomere, occiput with a dorsolateral crease, and other characters.
Graptomyza is a genus of hoverflies.
Peradon is a genus of hoverfly from the Neotropical realm, containing 31 species. Many of the species were originally described in the genus Microdon.
