Aulocara femoratum
Whitecrossed Grasshopper, White Cross Grasshopper, White-crossed Grasshopper
Aulocara femoratum, commonly known as the whitecrossed grasshopper, is a medium-sized slant-faced grasshopper inhabiting western North American grasslands. It is a generalist grass feeder that occasionally reaches pest status in mixedgrass prairie habitats, though it is typically subdominant to its congener Aulocara elliotti. The species exhibits sexual dimorphism in both size and feeding behavior, with males being smaller and more mobile while females are larger and more sedentary. It completes one generation annually, overwintering as eggs.
Cordillacris
Cordillacris is a genus of slant-faced grasshoppers in the family Acrididae, established by Rehn in 1901. The genus contains two described species: Cordillacris crenulata (crenulated grasshopper) and Cordillacris occipitalis (spot-winged grasshopper). Both species are small, slender grasshoppers of western North American grasslands. The genus is characterized by distinctive wing patterns and coloration that distinguish it from related genera.
Cordillacris crenulata
Crenulated Grasshopper, Crenulatewinged Grasshopper
Cordillacris crenulata is a small, slender slant-faced grasshopper native to western North American grasslands. It is distinguished by the diagnostic crenulate (scalloped) brown stripe on each tegmen. The species is a specialist feeder on blue grama grass and reaches greatest abundance in shortgrass and desert prairies. Though occasionally present in outbreak populations, its small size and typically low densities limit its economic impact.
Hadrotettix
Hadrotettix is a genus of band-winged grasshoppers in the family Acrididae, established by Scudder in 1876. The genus contains at least four described species distributed across western North America, including the well-documented Hadrotettix trifasciatus (three-banded grasshopper). Members are characterized by banded wing patterns and association with grassland habitats. The genus belongs to the tribe Hippiscini within the subfamily Oedipodinae.
