Steiroxys trilineatus
Three-lined Shieldback, Three-lined Camel Cricket
Steiroxys trilineatus is a shieldback katydid native to western North America, recognized by the three pale longitudinal stripes running along its dorsal surface. This flightless, ground-dwelling species inhabits grassland and sagebrush steppe ecosystems, where it occupies a cryptic lifestyle among vegetation and litter. Adults are active during summer months, with males producing songs via tegminal stridulation to attract mates. The species has been documented from the Great Basin through the Rocky Mountain region, with populations adapted to semi-arid conditions.
Stethophyma gracilis
Graceful Grasshopper
Stethophyma gracilis is a grasshopper species in the subfamily Gomphocerinae, native to western North America. It inhabits moist meadows and grasslands, particularly in montane and subalpine regions. The species is characterized by its slender body form and relatively long wings. Populations are typically found at higher elevations compared to many other grasshopper species in the region.
Tettigoniidae
katydids, bush crickets, long-horned grasshoppers
Tettigoniidae is a large family of orthopteran insects containing over 8,000 described species, commonly known as katydids in North America and bush crickets in the United Kingdom. The family is the only extant member of the superfamily Tettigonioidea within the suborder Ensifera. Members are characterized by extremely long, thread-like antennae that often exceed body length, distinguishing them from true grasshoppers. The family exhibits remarkable diversity in size, ranging from 5 mm to 130 mm, and occupies varied habitats from tropical rainforests to temperate grasslands across all continents except Antarctica.
Tettigoniidea
Katydids, wētā, and allies, katydids, wētā, bush crickets, king crickets, grigs
Tettigoniidea is an infraorder of Orthoptera comprising katydids, wētā, king crickets, and grigs. It includes six extant families distributed across four superfamilies: Tettigonioidea (katydids), Stenopelmatoidea (wētā and king crickets), Hagloidea (grigs), and the extinct Phasmomimoidea. Members are characterized by elongated antennae, enlarged hind legs adapted for jumping, and sound production via stridulation. The group contains at least 440 described species, with substantial diversity in tropical and temperate regions worldwide.
Tropisternus columbianus
water scavenger beetle
Tropisternus columbianus is a water scavenger beetle in the family Hydrophilidae. It is known to produce sound through stridulation, a behavior studied in western Oregon populations alongside congeneric species. The species occurs across western North America and has been recorded in aquatic and semi-aquatic habitats.
Tropisternus lateralis
Lateral-lined Water Beetle
Tropisternus lateralis is a hydrophilid water beetle with a broad distribution across the Americas, ranging from Canada through the United States, Mexico, and South America to the Caribbean. Studies of subspecies T. lateralis nimbatus in Texas playas documented colonization from surrounding aquatic habitats during flood periods, drought avoidance through aerial dispersal, and secondary production of 1.31 g/m²/0.25 year. Males of the related subspecies T. lateralis limbalis produce species-specific stridulatory sounds used in male-male interactions and possibly mate attraction.
