The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded, there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies.
Rhinophorinae is a subfamily of flies (Diptera), commonly known as Woodlouse Flies, found in all zoogeographic regions except Oceania, but mainly in the Palaearctic and Afrotropical regions.
Taeniopterygidae are a family of stone flies with about 110 described extant species. They are commonly called willowflies or winter stoneflies and have a holarctic distribution. Adults are usually smaller than 15 mm.
Tramea is a genus of dragonflies in the family Libellulidae, the skimmers and perchers. Species of Tramea are found in tropical and subtropical regions around the globe. They typically have colored bases to their otherwise translucent hindwings. In particular when they fly, this creates the impression of their carrying bags at the start of their abdomens. They are known commonly as saddlebags or saddlebags gliders.
Germaria is a genus of flies in the family Tachinidae.
Arctoperlaria is a suborder of stoneflies, with a World-wide distribution. The Plecoptera Species File divides this suborder as follows:
Voriini is a tribe of flies in the family Tachinidae. More junior homonyms exist of Wagneria than any other animal genus name.
Dexiinae is a subfamily of flies in the family Tachinidae.
Dexiini is a tribe of flies in the family Tachinidae.
Exoristinae is a subfamily of flies in the family Tachinidae. Most species are parasitoids of caterpillars.
Blondeliini is a tribe of parasitic flies in the family Tachinidae. Larvae are parasitoids of other insects, mostly beetles and caterpillars. Although nearly cosmopolitan, its greatest diversity is in the New World and especially in South America.
Goniini is a tribe of parasitic flies in the family Tachinidae. Members of Goniini are distinguished from other Tachinidae by laying small "microtype" eggs that hatch only after being ingested by a host.
Mesoleuctra is a genus of stoneflies that lived in the Jurassic period.
Alexandrinia is an extinct genus of mayflies which existed in what is now Russia and the United States during the Permian period. It was described by N. D. Sinitshenkova and D. V. Vassilenko in 2012, and contains four species: A. gigantea, A. directa, A. ipsa and A. vitta.
Misthodotes is an extinct genus of mayflies which existed during the Permian of what is now the United States and Russia. It was described by E.H. Sellards in 1909. A new species, M. tshernovae, was described from the Upper Permian epoch of Russia by N. D. Sinitshenkova and D. V. Vassilenko in 2012.
Hammephemera is an extinct genus of mayflies which existed during the early Triassic in what is now Nepal. It was described by Nina Sinitshenkova in 2012, and the type species is H. pulchra. The forewings measure approximately 8.75 millimetres by 4.06 millimetres.
Tachininae is a subfamily of flies in the family Tachinidae.
The Leuctridae are a family of stoneflies. They are known commonly as rolled-winged stoneflies and needleflies. This family contains at least 390 species.
Siphluriscidae is a family of mayflies. It contains a single extant species, Siphluriscus chinensis, which is native to Vietnam and China. It is thought to be the most primitive living lineage of mayflies. A fossil genus, Stackelbergisca is known from several species from the Jurassic and Early Cretaceous of Asia. A second species of Siphluriscus,S. davidi was later assigned to the genus Siphlonurus.
