*Superfamily

Muscoidea Muscoidea is a superfamily of flies in the subsection Calyptratae. Muscoidea, with approximately 7000 described species, is nearly 5% of the known species level diversity of the Diptera, the true flies. Most muscoid flies are saprophagous, coproph ...

Anthomyiidae The Anthomyiidae are a large and diverse family of Muscoidea flies. Most look rather like small houseflies, but are commonly drab grey. The genus ''Anthomyia'', in contrast, is generally conspicuously patterned in black-and-white or black-and- ...

Fanniidae The Fanniidae are a small (285 species in five genera) group of true flies largely confined to the Holarctic and temperate Neotropical realms; there are 11 Afrotropical species, 29 Oriental, and 14 Australasian. Adults are medium-sized to small ...

Muscidae Muscidae are a family of flies found in the superfamily Muscoidea. Muscidae, some of which are commonly known as house flies or stable flies due to their synanthropy, are worldwide in distribution and contain almost 4,000 described species i ...

Mystacinobiidae The New Zealand bat fly (''Mystacinobia zelandica'') is a small, wingless insect which lives in a commensal relationship with the New Zealand lesser short-tailed bat. It is a true fly, in the order Diptera, placed in its own genus, ''Mystacinobia ...

Oestridae Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. ''Dermatobia homin ...

Rhinophoridae Rhinophoridae is a family of flies (Diptera), commonly known as Woodlouse Flies, found in all zoogeographic regions except Oceania, but mainly in the Palaearctic and Afrotropical regions. They are small, slender, black, bristly flies phylog ...

Sarcophagidae Sarcophagidae () are a family of flies commonly known as flesh flies. They differ from most flies in that they are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or op ...

Ulurumyiidae ''Ulurumyia macalpinei'' is a species of fly in the superfamily Oestroidea endemic to Australia. It was first discovered in the 1970s, but was not described until 2017, and in the intervening decades was informally known to entomologists as McAlp ...
