Nomotettix cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.

parvus
low-ridged pygmy grasshopper
Nomotettix parvus is a species of pygmy grasshopper in the family Tetrigidae, described by Morse in 1895. It is known from the low-ridged pygmy grasshopper common name and occurs in North America. The species belongs to a family with over 2,000 described species, characterized by minute body size and often grotesque pronotal modifications. Like other Tetrigidae, it has been present since before the extinction of dinosaurs, with the family lineage extending over 230 million years.
Paratettix aztecus
Aztec pygmy grasshopper
Paratettix aztecus is a pygmy grasshopper in the family Tetrigidae, one of more than 2000 described species in this ancient family that has existed for over 230 million years. The species occurs from the southern Nearctic region into the northern Neotropics. Like other tetrigids, it is minute in size and associated with moist habitats near water. The species has been documented with 54 research-grade observations on iNaturalist as of 2021, indicating it is among the more frequently recorded pygmy grasshoppers in its range despite being far less studied than European and North American congeners.
Paratettix cucullatus
hooded grouse locust
Paratettix cucullatus, commonly known as the hooded grouse locust, is a species of pygmy grasshopper in the family Tetrigidae. It is a small, jumping insect found in North America, particularly in the central United States. The species is one of the better-known members of the genus Paratettix in the Nearctic region, with over 500 observations documented on citizen science platforms.
Paratettix mexicanus
Mexican pygmy grasshopper
Paratettix mexicanus is a species of pygmy grasshopper in the family Tetrigidae. It is one of the most frequently observed Tetrigidae species in North America on citizen science platforms. The species belongs to a family that has existed for over 230 million years, making pygmy grasshoppers one of the oldest lineages of modern insects.
Paratettix toltecus
Toltec pygmy grasshopper, Toltecan grouse locust
Paratettix toltecus is a small pygmy grasshopper in the family Tetrigidae, distinguished by its minute body size and elongated pronotum that extends over the abdomen. The species occurs across a broad geographic range spanning North, Central, and South America. Like other members of Tetrigidae, adults are often mistaken for juvenile insects due to their diminutive stature. The family Tetrigidae represents an ancient lineage with fossil records extending over 230 million years.
Tetrigidae
pygmy grasshoppers, groundhoppers, pygmy devils, grouse locusts
Tetrigidae is an ancient family of minute orthopterans with over 2,000 described species and a fossil record extending more than 230 million years. Members are characterized by an elongated pronotum that extends backward over the abdomen, often reaching the wing tips. The family exhibits exceptional morphological diversity, particularly in tropical regions where species display elaborate pronotal modifications including leaf mimicry, spines, and horns. Despite their ancient lineage and species richness, Tetrigidae remain among the most understudied orthopteran families.
Tetrix arenosa
Obscure pygmy grasshopper, Obscure grouse locust
Tetrix arenosa is a Nearctic species of pygmy grasshopper in the family Tetrigidae, one of approximately 35 tetrigid species in North America. Adults are minute, typically around 1 cm in length, with the pronotum extending backward over the abdomen—a characteristic feature of the family. The species has been documented in at least 82 iNaturalist research-grade observations, placing it among the more frequently recorded North American pygmy grasshoppers. Two subspecies are recognized: T. a. arenosa and T. a. angusta.
Tetrix subulata
Slender Ground-hopper, Slender Groundhopper, Awl-shaped Pygmy Grasshopper, Slender Grouse Locust
Tetrix subulata is a small groundhopper (family Tetrigidae) with a Holarctic distribution spanning the Palearctic and Nearctic regions. The species exhibits striking polymorphism in both coloration and wing development, with long-winged (macropterous) and short-winged (brachypterous) morphs coexisting in populations. It is strongly associated with moist habitats, particularly wet meadows, riverbanks, and mudflats, where it feeds primarily on algae and mosses. The species has been extensively studied for its wing dimorphism, reproductive interference with congeners, and life-history trade-offs between flight capability and reproduction.
Tettigidea
groundhoppers, pygmy grasshoppers
Tettigidea is a genus of pygmy grasshoppers in the family Tetrigidae, tribe Batrachideini. The genus contains at least 40 described species distributed across the Americas, from the United States through Mexico to South America. Members are characterized by their small size, cryptic coloration, and the distinctive pronotum that extends backward over the abdomen.
