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.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae.
Roesel's bush-cricket, Roeseliana roeselii is a European bush-cricket, named after August Johann Rösel von Rosenhof, a German entomologist.
Gryllus campestris, the European field cricket or simply the field cricket in the British Isles, is the type species of crickets in its genus and tribe Gryllini. These flightless dark colored insects are comparatively large; the males range from 19 to 23 mm and the females from 17 to 22 mm.
Meconema thalassinum is an insect in the family Tettigoniidae known as the oak bush-cricket and drumming katydid. It is native to Europe, including the British Isles, and was introduced to the United States, first established in the west of Long Island and extending its range to Rhode Island and Scarsdale, Stony Brook, and Ithaca, New York.
Gryllotalpa gryllotalpa, commonly known as the European mole cricket, is widespread in Europe and has been introduced to the eastern United States. The scientific name is 'mole cricket', derived from the Latin 'gryllus' (cricket); and 'talpa' (mole), because of the fine dense fur which covers it and its subterranean habits, and because of the mole-like forelegs adapted for digging, a good example of convergent evolution.
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms, "crickets" were placed at the family level, but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets.
Phaneroptera nana, common name southern sickle bush-cricket, is a species in the family Tettigoniidae and subfamily Phaneropterinae. It has become an invasive species in California where it may be called the Mediterranean katydid.
Tettigonia cantans is a species of bush crickets belonging to the family Tettigoniidae subfamily Tettigoniinae.
Yersinella raymondii, common name Raymond's bush-cricket, is a species of "katydids crickets" belonging to the family Tettigoniidae subfamily Tettigoniinae. The scientific name Yersinella comes from the name of the entomologist who has described the species in 1860.
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.
Pholidoptera griseoaptera, the dark bush-cricket, is a flightless species of European bush-cricket; it is the type species of its genus with no subspecies.
Oecanthus pellucens, common name Italian tree cricket, is a species of tree crickets belonging to the family Gryllidae, subfamily Oecanthinae.
Leptophyes is a genus of bush-crickets found in Africa, Asia, and Europe. The genus was erected by Franz Xaver Fieber in 1853.
Leptophyes laticauda is a species of bush-crickets belonging to the family Tettigoniidae.
Nemobius sylvestris, the wood cricket, is a flightless species of cricket in the family Trigonidiidae. It is native to Western Europe and North Africa but uncommon in Britain.
Caedicia simplex is a species of bush cricket or katydid, native to New Zealand and Australia. A common name is the "common garden katydid".
