Tetrix [1] is a genus of ground-hoppers or pygmy grasshoppers in the family Tetrigidae. There are at least 180 described species in Tetrix. [2] [3] [4] [5]
Orthoptera is an order of insects that comprises the grasshoppers, locusts and crickets, including closely related insects such as the katydids and wetas. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts and close relatives; and Ensifera – crickets and close relatives.
Tetrix may refer to:
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets (Tridactyloidea). The latter should not be confused with the mole crickets (Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera.
Tetrigidae is an ancient family in the order Orthoptera, which also includes similar families such as crickets, grasshoppers, and their allies. Species within the Tetrigidae are variously called groundhoppers, pygmy grasshoppers, pygmy devils or "grouse locusts".
Tettigidea is a genus of pygmy grasshoppers in the family Tetrigidae. There are at least 40 described species in Tettigidea found in the Americas.
Tetrix ceperoi, Cepero's groundhopper, is a member of the family Tetrigidae and is very similar to common grasshoppers. Grasshopper is defined as a "plant eating insect with long hind legs that are used for jumping and for producing a chirping sound". However, unlike the common grasshopper, the wings of T. ceperoi extend beyond its pronotum. The front wings have evolved throughout history to be stumps, and the back wings are very well developed. Thanks to the front wings only, T. ceperoi is capable of flying. Furthermore, T. ceperoi sports wide shoulders while covering its narrow abdomen beneath the pronotum. T. ceperoi are classified as Orthoptera, which describes crickets, grasshoppers, and locusts. Furthermore, these Orthoptera have incomplete metamorphosis, which also affects sexual dimorphism later. T. ceperoi reach an average length of about 10 millimetres (0.39 in). T. ceperoi is a multi-coloured ground dweller with the ability to blend into its surroundings. The ability of T. ceperoi to be different colours makes it able to evolve colour schemes better adapted to specific habitats. This cryptic nature of their outer layer provides protection from predators as it is able to blend into its surroundings. T. ceperoi is diurnal, which means it is solely active in the daytime. However, although it is diurnal, it continues to hibernate during a late nymphal instar or later on in life as adults.
Tetrix subulata is a species of groundhopper known as the slender ground-hopper, awl-shaped pygmy grasshopper and the slender grouse locust. It is found across the Palearctic: in North America, across much of Europe and Asia, from the British Isles east to Siberia, and to the southern parts of North Africa.
Tetrix undulata, the common ground-hopper, is a species of groundhopper in the Orthoptera: Caelifera.
Tettigidea acuta, the acute pygmy grasshopper, is a species of pygmy grasshopper in the family Tetrigidae. It is found in North America.
Paratettix is a genus of ground-hoppers or pygmy grasshoppers, with more than 60 described species found worldwide.
Tetriginae is a large subfamily of groundhoppers or pygmy grasshoppers. Members of Tetriginae occur on every continent except Antarctica.

Neotettix is a genus of pygmy grasshoppers in the family Tetrigidae. There are four described species in Neotettix: all from North America.
Tetrix arenosa, known generally as the obscure pygmy grasshopper or obscure grouse locust, is a species of pygmy grasshopper in the family Tetrigidae. It is found in North America.
Neotridactylus is a genus of pygmy mole crickets in the family Tridactylidae. There are about 16 described species in Neotridactylus.
Tetrix brunneri, known generally as the brunner pygmy grasshopper or Brunner's grouse locust, is a species of pygmy grasshopper in the family Tetrigidae. It is found in North America.
