Carnoidea is asuperfamily ofAcalyptrataeflies.
In general, member of Carnoidea are small flies no more than a few millimetres long.[1][2][3]
Carnoidea is a poorly defined superfamily. In 1989, tensynapomorphies were described for the group,[4] but most of these have later been challenged. As of 2006, the following synapomorphies were described: uppermost fronto-orbital bristle(s) of the head is exclinate; phallus of the male is flexible, unsclerotized, simple and elongate; and phallus is microtrichose.[3]
Braulidae are associated withhoney bees, with larvae developing inbeeswax while adults attach to bees and feed from bee mouthparts.[5]
Canacidae adults are mainly found on seashore habitats such as beaches,estuarine tidal flats, wave-swept rocks andmangroves. Little is known about their larvae, but they are believed to mainly feed onalgae in the intertidal zone.[6] Australimyzidae are also found on seashores, being associated with dead or decaying plant matter.[7]
Carnidae arescavengers found in various kinds of plant matter, animal dung, carrion and vertebrate nests. Milichiidae are also scavengers and most occur in a range of habitats, though some are restricted to ant nests, bee nests or bat dung in caves.[5]
Chloropidae are more varied in their larval ecology, including scavengers,herbivores in plant shoots and stems (these may be largelybacterial feeders), parasites feeding on frog blood, andpredators of insect or spider eggs.[2]
Adults of Inbiomyiidae are believed to be microbial grazers, as dissections have found fungal, algal and probably bacterial material in their guts. The larvae are unknown.[3]
Australimyzidae and Inbiomyiidae aresister groups, meaning they are more closely related to each other than to any other family.[3]
Carnoidea may not be amonophyletic group. One molecular analysis found that its constituent families are more closely related to members of other superfamilies, such as Braulidae toDrosophilidae (superfamilyEphydroidea).[8]
