See text The Tettigoniinae are a subfamily of bush crickets or katydids, which contains hundreds of species in about twelve tribes.

[1] The greatest diversity is in the Palaearctic region[1] and many of the familiar European species of bush crickets (e.g. in the genera Metrioptera, Pholidoptera, Platycleis and the type genus Tettigonia) are in this subfamily.

[2] Extant genera are native to: the Americas (where they may be called shield-backed katydids[citation needed]), Australia, southern Africa, Europe (especially Mediterranean), and the Near East.

Brunner von Wattenwyl, 1893; distribution: Nearctic, Palaearctic, probably through to Australasia Auth.

Krauss, 1902; distribution: Nearctic, Palaearctic, possibly through to Australasia The Mormon cricket, actually a katydid and member of this subfamily, has been known to cause extensive damage when it breeds in large numbers in cropland.
