Camelids are members of the biological family Camelidae, the only currently living family in the suborder Tylopoda. The seven extant members of this group are: dromedary camels, Bactrian camels, wild Bactrian camels, llamas, alpacas, vicuñas, and guanacos. Camelids are even-toed ungulates classified in the order Artiodactyla, along with species including whales, pigs, deer, cattle, and antelopes.
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave crickets, camel crickets, spider crickets, and sand treaders. Those occurring in New Zealand are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described.
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.
The ashy storm petrel is a small, scarce seabird of the storm petrel family Hydrobatidae. It breeds colonially on islands off the coasts of California and Mexico, and is one of six species of storm petrel that live and feed in the rich California Current system.
Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants.
Hadenoecus is a genus of common cave cricket of the southeastern United States and typical of the tribe Hadenoecini.
Diestrammena is a 'camel' or 'cave-cricket' genus in the family Rhaphidophoridae. Species in the genus are native to Asia, including Japan.
Ceuthophilus is a genus of insects in the cave cricket family Rhaphidophoridae. It contains most of the species that are known commonly as camel crickets.
Euhadenoecus is a genus of camel crickets in the family Rhaphidophoridae. There are at least four described species in Euhadenoecus.
Hadenoecus subterraneus, the common cave cricket, or Mammoth Cave cricket is a species of camel cricket in the family Rhaphidophoridae. It is found in North America.
Gammarotettix is a North American genus of camel crickets in the family Rhaphidophoridae. They are also called chaparral camel crickets or arboreal camel crickets and are between 10–18 mm. They live mainly in California and possibly in southern Oregon and Arizona.
Styracosceles is a genus of camel crickets in the family Rhaphidophoridae. There are at least four described species in Styracosceles.
Paradiestrammena is a genus of cave or camel crickets in the subfamily Aemodogryllinae and tribe Aemodogryllini. Originating in Asia, species have been found in Borneo, the Indo-China region and Japan.
Atachycines is a genus of cave or camel crickets in the subfamily Aemodogryllinae; the genus has not been assigned to any tribe. Originating in Asia, species have been found in Borneo, the Indo-China region and Japan.
Tamdaotettix is a genus of cave or camel crickets in the subfamily Aemodogryllinae and tribe Diestramimini. Originating in Asia, species have been found in the Indo-China region.
Wētā is the common name for a group of about 100 insect species in the families Anostostomatidae and Rhaphidophoridae endemic to New Zealand. They are giant flightless crickets, and some are among the heaviest insects in the world. Generally nocturnal, most small species are carnivores and scavengers while the larger species are herbivorous. Although some endemic birds likely prey on them, wētā are disproportionately preyed upon by introduced mammals, and some species are now critically endangered.
Ceratobiton is a monotypic genus of daesiid camel spiders, first described by Delle Cave and Simonetta in 1971. Its single species, Ceratobitonstyloceros is distributed in Israel and Jordan.
Speleotettix is a genus of cave/camel crickets in the subfamily Macropathinae established by Chopard in 1944.
Novotettix is a monotypic genus of cave cricket/wētā in the family Rhaphidophoridae endemic to south-east Australia.
Tachycines asynamorus is a cave cricket and the type species of the genus Tachycines (Rhaphidophoridae). In English-speaking countries it is known as the greenhouse camel cricket or greenhouse stone cricket for its propensity for living in greenhouses. It was first described in 1902 by Russian entomologist Nicolai Adelung on the basis of specimens caught in the palm houses of St. Petersburg. Some authorities have placed this species in the genus Diestrammena, but it has now restored to its basonym.
