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 open wounds of mammals, hence their common name. Some flesh fly larvae are internal parasites of other insects such as Orthoptera, and some, in particular the Miltogramminae, are kleptoparasites of solitary Hymenoptera. The adults mostly feed on fluids from animal bodies, nectar, sweet foods, fluids from animal waste and other organic substances. Juveniles need protein to develop and may be laid on carrion, dung or sweet plant foods.
Sphaeroceridae are a family of true flies in the order Diptera, often called small dung flies, lesser dung flies or lesser corpse flies due to their saprophagous habits. They belong to the typical fly suborder Brachycera as can be seen by their short antennae, and more precisely they are members of the section Schizophora. There are over 1,300 species and about 125 genera accepted as valid today, but new taxa are still being described.
Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds. In this family, the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic. As usual in their superfamily Hippoboscoidea, most of the larval development takes place within the mother's body, and pupation occurs almost immediately.
Braulidae, or bee lice, is a family of true flies (Diptera) with seven species in two genera, Braula and Megabraula. They are found in honey bee colonies due to their phoretic, inquiline, and kleptoparasitic relationships with the bees. Similar in appearance but not closely related to keds, these flies are also small, wingless, and occasionally mistaken for mites or lice, hence their common name.
Carnoidea is a superfamily of Acalyptratae flies.
Xylomyidae is a family of flies known commonly as the wood soldier flies. They are xylophagous and are associated with dead or dying wood.
Rhagionidae or snipe flies are a small family of flies. They get their name from the similarity of their often prominent proboscis that looks like the beak of a snipe.
Carnidae, also known as bird flies or filth flies, is a family of flies (Diptera). There are 6 genera, containing about 93 species worldwide.
The Pyrgotidae are an unusual family of flies (Diptera), one of only two families of Cyclorrhapha that lack ocelli. Most species are "picture-winged", as is typical among the Tephritoidea, but unlike other tephritoids, they are endoparasitoids; the females pursue scarab beetles in flight, laying an egg on the beetle's back under the elytra where the beetle cannot reach it. The egg hatches and the fly larva enters the body cavity of the beetle, feeding and eventually killing the host before pupating. In the United States, some species of Pyrgota and Sphecomyiella can be quite common in areas where their host beetles are abundant. Like their host beetles, these flies are primarily nocturnal, and are often attracted to artificial lights.
Lonchoptera is a genus of spear-winged flies (Lonchopteridae). Their common name refers to their subacute (pointed) wings, which have a distinct and sexually dimorphic venation.
Platensina is a genus of tephritid or fruit flies in the family Tephritidae.
There are various disparate groups of wingless insects. Apterygota are a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history. They include Thysanura . Some species lacking wings are members of insect orders that generally do have wings. Some do not grow wings at all, having "lost" the possibility in the remote past. Some have reduced wings that are not useful for flying. Some develop wings but shed them after they are no longer useful. Other groups of insects may have castes with wings and castes without, such as ants. Ants have alate queens and males during the mating season and wingless workers, which allows for smaller workers and more populous colonies than comparable winged wasp species.
Bolitophila is the sole living genus in the Bolitophilidae, a family of Diptera in the superfamily Sciaroidea, with around 40 Palaearctic and about 20 Nearctic species, and three species from the Oriental region (Taiwan). They are small (6–9 mm).
Melaloncha is a genus of phorid flies commonly referred to as "bee-killing flies". They are found almost exclusively in the Neotropical realm, although there is one record from extreme southern Texas, United States. They are small flies, usually about 2–3 millimetres (0.08–0.12 in) in length. No true fossils are known, although there are some specimens in Colombian copal, of unknown age.
The Metopininae are a subfamily of flies in the family Phoridae.
Carnus is a genus of flies (Diptera) with 5 described species, all of which are parasites of birds. The adult flies locate a suitable host nest, then shed their wings and feed on the blood of the developing nestlings. Mature female flies lay their eggs in the nest, where their larvae develop on organic detritus.
Copromyzinae is a subfamily of flies belonging to the family Lesser Dung flies.
Leptocera is a genus of flies belonging to the family Lesser Dung flies.
Terrilimosina is a genus of flies belonging to the family of the Lesser Dung flies.
Braula coeca, the bee louse, is a species of bee louse in the family Braulidae.
