The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years : taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Francis Walker.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae.
Myrmecophilus or ant crickets, is a genus of orthopteran insects in the family Myrmecophilidae. This genus contains the majority of myrmecophilous (ant-loving) species in this small, obscure family.
Tree crickets are insects of the order Orthoptera. These crickets are in the subfamily Oecanthinae of the family Gryllidae.
Trigonidiinae is a subfamily of insects in the order Orthoptera, suborder Ensifera, based on the type genus Trigonidium. They are often referred to as sword-tail crickets, winged bush crickets or trigs.
Phalangopsinae, occasionally known as spider crickets, are a subfamily of crickets in the family Phalangopsidae. Members of Phalangopsinae are found worldwide in tropical and subtropical regions. Most species in the subfamily are nocturnal and can be found in rocky areas, near fallen wood, and the understory of forests. Some species are gregarious, gathering in large numbers.
Teleogryllus is a genus of crickets in the family Gryllidae. Species can be found in Africa, Asia, Australia and the Pacific islands.
The Eneopterinae are a subfamily of crickets, in the family Gryllidae, based on the type genus Eneoptera. It is one of several groups widely described as "true crickets". Of the more than 500 species that make up this subfamily, most occur in moist, tropical habitats. These insects are medium to large and brown or gray in color. They eat plant leaves, flowers, and fruits and can occasionally cause economic damage. Their eggs are deposited in pith, bark, or wood. Eneopterinae show a great diversity in stridulatory apparatus, signals emitted, and associated behaviour.
Nemobiinae is a subfamily of the newly constituted Trigonidiidae, one of the cricket families. The type genus is Nemobius, which includes the wood cricket, but members of this subfamily may also be known as ground crickets or "pygmy field crickets".
Loxoblemmus is a genus of crickets in tribe Gryllini. Species can be found in Africa, Asia and Australia.
Hapithinae is a subfamily of insects in the cricket family Gryllidae. It is one of several groups referred to in American English as "bush crickets", although this term can be confused with the Tettigoniidae.
Podoscirtinae is a subfamily of crickets in the family Gryllidae.
Trigonidium is a large genus of sword-tail crickets, typical of the tribe Trigonidiini. Records of occurrence are from Europe, Africa, tropical Asia, Australia and the Pacific islands; many species endemic to Pacific islands including Hawaii have now been placed in the genus Nudilla.
Pteronemobius is a genus of crickets in the subfamily Nemobiinae, with a worldwide distribution.
The Phalangopsidae are a recently reconstituted family of crickets, based on the type genus PhalangopsisServille, 1831 from South America. Priority for family-group names based on this genus dates from Blanchard's "Phalangopsites".
The Phaloriinae is a subfamily of crickets of the family Phalangopsidae. Species are terrestrial and are distributed in: Africa, tropical Asia, Korea, Australia and the Pacific Islands.
Gryllini is a tribe of crickets and typical of the family Gryllidae. Species are terrestrial, carnivorous or omnivorous and can be found in all continenents except Antarctica.
Turanogryllus is a genus of crickets in the family Gryllidae and tribe Turanogryllini. Species can be found in Africa, Greece in Europe and throughout Asia.
Duolandrevus is a genus of crickets in the subfamily Landrevinae and tribe Landrevini. Species can be found in Asia.
The Gryllomorphinae are a subfamily of crickets based on the type genus Gryllomorpha. Species have been recorded from: North Africa and the western Palaearctic (mainland).
