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.
Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules being moved across a finely-ridged surface or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include chirp and chirrup.
Roesel's bush-cricket, Roeseliana roeselii is a European bush-cricket, named after August Johann Rösel von Rosenhof, a German entomologist.
Chorthippus jutlandica, the Jutland bow-winged grasshopper, is a species of grasshopper in the subfamily Gomphocerinae. It is endemic to sparsely vegetated coastal sand dunes in an area covering only 87 km2 (34 sq mi) between Blåvandshuk and Hvide Sande in western Jutland, Denmark, but it is common and not considered to be under any threat.
The speckled bush-cricket is a flightless species of bush-cricket belonging to the family Tettigoniidae. The species was originally described as Locusta punctatissima in 1792.
Chorthippus is a large genus of acridid grasshoppers with around 230 described species. The genus may be subdivided into subgenera including: Altichorthippus, Chorthippus and Glyptobothrus, with other species not placed.
Chorthippus brunneus, also known as the common field grasshopper, is a species of grasshopper of the subfamily Gomphocerinae. The species is common and widespread in the Western Palearctic, and the IUCN lists it as Least Concern.
Pseudochorthippus parallelus, the meadow grasshopper, is a common species of grasshopper in the tribe Gomphocerini. It is found in non-arid grasslands throughout the well vegetated areas of Europe and some adjoining areas of Asia. It is a well-studied organism in the discipline of evolutionary biology and was an early and important model system for the study of European phylogeography.
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.
Tettigonia viridissima, the great green bush-cricket, is a large species of bush-cricket belonging to the subfamily Tettigoniinae.
Chorthippus biguttulus, the bow-winged grasshopper, is one of the most common species of grasshopper found in the dry grassland of northern and central Europe. It is part of a group of species (biguttulus-group) that are very difficult to identify morphologically. Chorthippus biguttulus was previously classified as a single species Stauroderus variabilis. The three species were distinguished using song characteristics.
Arcyptera fusca, the large banded grasshopper, is a species of 'short-horned grasshoppers' belonging to the family Acrididae subfamily Gomphocerinae.
Spharagemon collare, the mottled sand grasshopper, is found in sandy-soiled, grassy areas of northern United States and southern Canada. They are known to be a minor pest of wheat crops; however, populations are rarely large enough to cause appreciable damage.
Tettigonia cantans is a species of bush crickets belonging to the family Tettigoniidae subfamily Tettigoniinae.
Omocestus viridulus, known in the British Isles as the common green grasshopper, is a Palearctic species of grasshopper in the subfamily Gomphocerinae.
The rufous grasshopper is a species of grasshopper. It is a medium-sized, broad, brown, short-horned grasshopper with clubbed antennae that are tipped with a conspicuous white or pale colour. It is fairly large, averaging 14 to 22 mm in length. It is of the subfamily Gomphocerinae in the family Acrididae, the predominant family of grasshoppers. This species is present in most of Europe, in the eastern Palearctic realm, and in the Near East. It can be encountered from late July through mid-December, usually in dry or slightly moist habitats. The environments in which it typically resides include dry grassland on calcareous soils, sheltered valleys with scrub, and the open borders of forests. It feeds on grasses and various herbaceous plants. It is known for its distinctive courtship song and accompanying display.
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.
Oecanthus pellucens, common name Italian tree cricket, is a species of tree crickets belonging to the family Gryllidae, subfamily Oecanthinae.
Dissosteira carolina, the Carolina grasshopper, Carolina locust, black-winged grasshopper, road-duster or quaker, is a band-winged species of grasshopper which ranges widely in North America inhabiting weedy grasslands.
