The subfamily Microdontinae contains slightly more than 400 species of hoverflies (family Syrphidae) 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 (some of these species have no functional mouthparts and cannot feed as adults). A number of genera (e.g. Masarygus, Paragodon, Schizoceratomyia and Surimyia) lack the "spurious vein" which is characteristic of all other Syrphidae. For other distinguishing characteristics, see Thompson (1969).
