About Stenodema trispinosa Reuter, 1904
Species in the genus Stenodema are elongated bugs, and have a longitudinal furrow between the eyes. They can be best distinguished by their coarsely and densely pitted prothorax. This species, which was originally mislabeled as S. pilosa here, has a body length of about 8–9 mm, and has three spurs on its hind femora. This characteristic separates it from closely related species, most notably S. calcarata, which only has two spurs on its femora. This species has two generations per year. Adults that have overwintered and mated in the spring are green, with an orange-brown hourglass-shaped marking running down their back. Adults born later in the year are beige or tan. Males are often darker in color than females. This species is found transcontinentally across North America and Eurasia, and is commonly found in grassy fields and wetlands. This species feeds on grasses including meadow foxtail, reed canary grass, and common reed. It overwinters in the adult stage, emerges in April, and the full new generation is developed by August.
