Summary

Trimerotropis is a genus of band-winged grasshoppers, with species prevalent in North America. They are characterized by their slender bodies, distinctive wing markings, and ability to produce unique sounds when flying. The genus is likely to undergo redefinition as more is learned about species relationships.

Physical Characteristics

Mostly relatively slender, medium-sized (about 1 to 2 inches long). Pronotal ridge is cut twice, usually faint or absent on the posterior half. Front wings have dark markings, with dark cross bands or irregular dark spots. Hind wings have yellow, green, or blue coloration (never reddish) with a dark cross band and a spur. Hind femora usually show faint diagonal crossbands externally. Hind tibia can vary in color, including brown, blue, green, yellow, orange, red, or rarely purplish.

Identification Tips

Identify by comparing hind tibia color and wing markings. The presence of dark cross bands and the coloration of hind wings are critical for species identification. Crepitation sounds produced during flight can also assist in identification.

Habitat

Found in open sunny areas, typically in environments with bare ground or exposed rocks.

Distribution

Coast to coast across North America, primarily south of Boreal forests, with a majority located in western regions.
