California orange-winged grasshopper
Arphia ramona, the California orange-winged grasshopper, is a band-winged grasshopper species in the family Acrididae. It is characterized by orange hind wings that are concealed at rest but visible in flight. The species occurs in western North America, with a strong association with California habitats ranging from Coast Ranges to interior locations. Males produce a crackling sound during flight through wing crepitation, a trait associated with mating behavior.
Xanthippus corallipes corallipes
Redshanked Grasshopper, Red Shanks
A large rangeland grasshopper of western North America, adults are present in spring and are conspicuous due to loud crepitation during evasive flight. The subspecies exhibits strong flight capability and feeds almost exclusively on grasses and sedges. Populations normally remain at low densities but occasionally erupt into outbreaks that damage rangeland and crops. Northern populations have a two-year life cycle while southern populations complete development in one year.
