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.
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.
Roesel's bush-cricket, Roeseliana roeselii is a European bush-cricket, named after August Johann Rösel von Rosenhof, a German entomologist.

Saga pedo is a species of wingless bush cricket from the southern half of Europe and western and central Asia. This brown or green bush cricket typically has a total length, from the head to the tip of the ovipositor, of up to 10.5 cm (4.1 in), but exceptionally it may reach 12 cm (4.7 in), which makes it one of the largest European insects and one of the world's largest Orthoptera. The head-and-body alone typically is 5–7 cm (2.0–2.8 in) long in adults, but may reach up to 7.8 cm (3.1 in).
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.
Metaplastes pulchripennis, common name Italian ornate bush-cricket, is a species of 'katydids crickets' belonging to the family Tettigoniidae subfamily Phaneropterinae.
Tettigonia is the type genus of bush crickets belonging to the subfamily Tettigoniinae. The scientific name Tettigonia is onomatopoeic and derives from the Greek τεττιξ, meaning cicada.
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.

Ephippiger terrestris, common name Alpine saddle-backed bush-cricket, is a bush cricket species belonging to the family Tettigoniidae, subfamily Bradyporinae.
Platycleis grisea is a European species of bush crickets described by Fabricius in 1781. It is the type species of the genus Platycleis and therefore the tribe Platycleidini. This species is recorded from mainland Europe and northern Africa.
Polysarcus is a genus of bush crickets in the subfamily Phaneropterinae and tribe Barbitistini. Species can be found in western Europe, Middle East through to Afghanistan.
Siliquofera is a genus of bush cricket in the subfamily Phyllophorinae that includes only one species, Siliquofera grandis, which is fairly common and widespread in rainforest canopies of New Guinea and nearby smaller islands, and seemingly rare in Australia where only found in the remote Iron Range region. This very well-camouflaged, green and leaf-like bush cricket is one of the world's largest Orthoptera, with adults typically having a length of 10.7–13 cm (4.2–5.1 in) and a wingspan of 25–27 cm (9.8–10.6 in); it can weigh more than 30 g (1.1 oz).
