Ageneotettix deorum
white-whiskered grasshopper, white whiskers grasshopper, sand grasshopper
Ageneotettix deorum is a medium-sized slant-faced grasshopper widely distributed across North American grasslands. It is frequently the dominant species in mixedgrass and bunchgrass prairie outbreaks, reaching densities of 25 adults per square yard. The species exhibits early-season hatching with nymphal development spanning 40–48 days. Adults are ground-dwelling, diurnal herbivores that feed on grasses and ground litter. Population dynamics show sensitivity to weather and predation, with outbreaks typically building over 3–5 years followed by sudden crashes.
Eupnigodes
Eupnigodes is a genus of slant-faced grasshoppers in the family Acrididae. The genus contains at least two described species, both restricted to the western United States. As members of the subfamily Gomphocerinae and tribe Aulocarini, these grasshoppers share morphological features with related genera in this group. The genus was established by McNeill in 1897.
Psoloessa
brown-spotted range grasshopper (P. delicatula), Texas spotted range grasshopper (P. texana)
Psoloessa is a genus of slant-faced grasshoppers in the family Acrididae, subfamily Gomphocerinae. The genus contains at least four described species distributed across western North America, from British Columbia to Mexico. Two species—P. delicatula (brown-spotted range grasshopper) and P. texana (Texas spotted range grasshopper)—are documented in Colorado and Wyoming grasshopper surveys. Members of this genus are characterized by their slant-faced morphology typical of the Gomphocerinae.
