Aeropedellus arcticus
Arctic Grasshopper
Aeropedellus arcticus is a species of grasshopper in the family Acrididae, described by Hebard in 1935. It belongs to the genus Aeropedellus, commonly known as clubhorned grasshoppers due to their distinctive clavate antennae. The species epithet 'arcticus' suggests an association with arctic or high-latitude environments. As a member of the subfamily Gomphocerinae, it is part of a group characterized by slant-faced grasshoppers with specific antennal modifications. The species is known from Alaska and broader North America, though detailed biological studies appear limited compared to its congener A. clavatus.
Aeropedellus clavatus
Club-horned Grasshopper, Clubhorned Grasshopper, Slant-faced Grasshopper
Aeropedellus clavatus, commonly known as the club-horned grasshopper, is a medium-sized slant-faced grasshopper in the family Acrididae. It is distinguished by its club-shaped antennae, with the last six segments enlarged and darker than the rest. The species exhibits pronounced sexual dimorphism: females are flightless with short wings, while males may have either short or long wings, with long-winged males capable of flight. It is one of the earliest-hatching grasshoppers in its range, emerging in early spring and completing development rapidly. Populations are most abundant in the Canadian prairies, where it is the most widely distributed grassland grasshopper species.
Ageneotettix brevipennis
short-wing big-headed grasshopper
Ageneotettix brevipennis is a slant-faced grasshopper in the family Acrididae, distinguished by its notably short wings relative to body size.

Chorthippus is a large genus of gomphocerine grasshoppers comprising approximately 230 described species, predominantly distributed in the Palaearctic realm. The genus was erected by Franz Fieber in 1852 and has been subdivided into subgenera including Altichorthippus, Chorthippus, and Glyptobothrus. Many species within this genus are morphologically cryptic and difficult to distinguish visually, particularly in mainland Eurasia where song patterns serve as the primary means of species identification. The genus contains notable species groups such as the Chorthippus biguttulus group, which includes the common field grasshopper.
Cibolacris parviceps
Cream Grasshopper
Cibolacris parviceps, commonly known as the cream grasshopper, is a small grasshopper species in the family Acrididae. It inhabits arid and semi-arid environments of the southwestern United States and adjacent Mexico. The species is notable for its cryptic, stone-like coloration that provides effective camouflage in desert habitats. It overwinters as nymphs rather than eggs, an uncommon trait among North American grasshoppers.
Cibolacris parviceps parviceps
cream grasshopper
Cibolacris parviceps parviceps, commonly known as the cream grasshopper, is a small grasshopper species found in arid regions of the southwestern United States. Adults measure 20–32 mm in body length and exhibit cryptic coloration resembling granite or stone, providing effective camouflage in desert environments. The species inhabits dry desert washes, overgrazed rangeland, and disturbed areas including unpaved parking lots. Unlike many grasshoppers that overwinter as eggs, C. parviceps parviceps overwinters as nymphs, with adults present early in spring. The subfamily placement of this species has been revised from Oedipodinae to Gomphocerinae, though some authors note this classification remains puzzling.
