Insects in the family Tettigoniidae are commonly called katydids or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea.
Orthoptera is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives.
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.
Katydid is the common name in America for insects of the family Tettigoniidae, including
The wart-biter is a bush-cricket in the family Tettigoniidae. Its common and scientific names derive from the eighteenth-century Swedish practice of allowing the crickets to nibble at warts to remove them.
Acanthoplus discoidalis is a species in the Hetrodinae, a subfamily of the katydid family (Tettigoniidae). Like its closest relatives, Acanthoplus discoidalis variously bears common names such as armoured katydid, armoured ground cricket, armoured bush cricket, corn cricket, setotojane and koringkriek. The species is native to parts of Angola, Namibia, Botswana, Zimbabwe and South Africa.
Conocephalus fuscus, the long-winged conehead, is a member of the family Tettigoniidae, the bush-crickets and is distributed through much of Europe and temperate Asia. This bush-cricket is native to the British Isles where it may confused with the short-winged conehead. These two species are phenotypically similar; however, the distinguishing factor between the two is the fully developed set of wings the long-winged conehead possesses that allows for flight. In the short-winged coneheads the hind wings are shorter than the abdomen, causing the wings to be vestigial and the species is incapable of flight. For this reason it is hard to discriminate between the two species during the early stages of their life cycle before the wings have fully developed. The colouration of the conehead is typically a grass green with a distinctive brown stripe down its back, though there are some brown phenotypes.
Panoploscelis is a genus of very large insects belonging to the true katydid tribe Eucocconotini, which is a subfamily of the Tettigoniidae. Like the other members of the suborder Ensifera, Panoploscelis are part of the insect order Orthoptera, which also contains crickets, grasshoppers and locusts. Members of this genus are among the largest katydids of the Neotropics.
Sathrophyllia is a genus of Asian bush crickets or katydids in the subfamily Pseudophyllinae and tribe Cymatomerini. They are usually found on the branches of bushes or trees where they sit close to a branch and spread out their forelegs and antennae along the branch and hold themselves close to the surface with their middle pair of legs. Some species like S. rugosa have cryptic colouration that matches the bark making them very hard to spot. Further east, the genus Olcinia also bears a close resemblance, however Sathrophyllia has a relatively smooth margin to the forewing unlike that of Olcinia.
Gryllus assimilis, commonly known as the Jamaican field cricket and sometimes referred to as the silent cricket among other names, is one of many cricket species known as a field cricket. Its natural habitats are the West Indies and parts of the southern United States, Mexico, and South America, though as a result of widespread breeding programs to supply feeder insects to the pet industry since 2010, it has become available commercially throughout North America and Europe.
Pseudophyllus titan, the giant false leaf katydid, is a species of leaf-mimic bush-cricket of the subfamily Pseudophyllinae found in the canopy of tropical forests in Mainland Southeast Asia, Bangladesh, northeastern India, and southernmost China (Yunnan). It is among the largest species in the genus Pseudophyllus, which also makes it one of the world's largest Orthoptera, with a typical length of 13 cm (5.1 in) from head to tip of the folded wings and a wingspan of c. 23 cm (9.1 in). Like many other species of crickets and grasshoppers, the male is capable of stridulation, producing a relatively loud and distinctive, bird-like chirp; it usually stridulates ("sings") at night.
Microcentrum retinerve is a species in the family Tettigoniidae ("katydids"), in the order Orthoptera. A common name for Microcentrum retinerve is lesser angle-winged katydid. Microcentrum retinerve is found in North America.
Scudderia curvicauda is a species in the family Tettigoniidae ("katydids"), in the order Orthoptera. A common name for Scudderia curvicauda is "curve-tailed bush katydid". Scudderia curvicauda is found in North America.
Scudderia pistillata is a species in the family Tettigoniidae ("katydids"), in the order Orthoptera. A common name for Scudderia pistillata is "broad-winged bush katydid". Scudderia pistillata is found in North America.
Capnobotes fuliginosus is a species of katydid known as the sooty longwing. It is found in the western United States and Mexico. It is omnivorous and it is the prey of the wasp Palmodes praestans.
Tettigoniidea is an infraorder of the order Orthoptera, with six extant families.
Orchelimum pulchellum, the handsome meadow katydid, is a species of meadow katydid in the family Tettigoniidae. It is found in North America.
Caedicia simplex is a species of bush cricket or katydid, native to New Zealand and Australia. A common name is the "common garden katydid".
Pterophylla is a genus of true katydids in the family Tettigoniidae. There are about five described species in Pterophylla.
Pterophyllini is a tribe of true katydids in the family Tettigoniidae. There are about 16 genera and more than 40 described species in Pterophyllini.
