Arphia conspersa
Speckle-winged Rangeland Grasshopper, Speckled Rangeland Grasshopper
Arphia conspersa is a large band-winged grasshopper (family Acrididae, subfamily Oedipodinae) distributed across western North America from Alaska to Mexico. Adults are active primarily in spring, distinguishing them seasonally from the related redwinged grasshopper (Arphia pseudonietana) which appears in late summer and fall. The species exhibits distinctive visual and acoustical courtship displays, with males performing aggregation flights accompanied by crackling crepitation. It inhabits diverse grassland habitats including prairies, desert shrub communities, and montane meadows up to 11,000 feet elevation.
Eritettix simplex
velvet-striped grasshopper, velvet-striped locust
Eritettix simplex, the velvet-striped grasshopper, is a medium-sized slant-faced grasshopper in the family Acrididae. It is characterized by distinctive velvet-like dark bands along the lateral carinae of the pronotum and three longitudinal carinae on the head. The species has an extensive range across North America, with major population centers in the Great Plains and Appalachian Mountains. It feeds almost exclusively on grasses and sedges, with blue grama being a highly preferred food plant.
Macrohomotoma gladiata
Curtain Fig Psyllid
Macrohomotoma gladiata is an invasive Asian psyllid that has established populations across the Mediterranean Basin and California, where it infests ornamental Ficus microcarpa. Nymphs feed on young tissues, producing dense white waxy secretions and honeydew that promotes sooty mould growth and causes twig dieback. The species has a likely bivoltine life cycle with possible partial third generation; young nymphs overwinter under stipules without development, resuming growth in spring. Natural enemies include a Psyllaephagus parasitoid that can achieve high parasitism rates, and the predatory bug Anthocoris nemoralis.
Psoloessa texana
Texas Range Grasshopper, Texas Spotted Range Grasshopper
Psoloessa texana is a species of slant-faced grasshopper in the family Acrididae. It is found in North America, with records from the southwestern United States and Mexico. The species belongs to the subfamily Gomphocerinae and is part of the tribe Aulocarini.
Xanthippus corallipes altivolus
Red shanks
Xanthippus corallipes altivolus is a subspecies of the redshanked grasshopper found from foothills to timberline in Colorado and western North America. Adults are medium to large, tan-colored grasshoppers with distinctive red inner hind femora and orange hind tibiae. This subspecies is distinguished from other X. corallipes subspecies by its high-elevation habitat. Populations can cause significant damage to rangeland grasses during outbreak years.
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.
Xanthippus corallipes leprosus
Redshanked Grasshopper
Xanthippus corallipes leprosus is a subspecies of the redshanked grasshopper, a large rangeland species native to western North America. Adults are conspicuous in spring, producing loud crepitation during evasive flight and displaying yellow, dark-banded wings. The subspecies exhibits geographic variation in life cycle duration, with northern populations completing development in two years and southern populations in one year. Adults feed almost exclusively on grasses and sedges, and while typically present at low densities, populations occasionally erupt to damaging levels.
