Populations of the Northern Bush Katydid, Scudderia septentrionalis, are found throughout the northeastern US. However, the North Carolina Natural Heritage Program lists the species as "significantly rare" in North Carolina because there are only two historical, state records for this species. Surveys for the katydid in western North Carolina were conducted by listening for their unique mating calls. Katydids were heard, recorded or collected from 13 different sites and six new county records for the state are reported. Males were collected and their songs were recorded at varying temperatures. Male songs consisted of two sound units, a series of rasp-like syllables and ticks. Although the mating calls are species-specific, the rates of both call units changed significantly with temperature. Duets between one male and a female were also recorded. S. septentrionalis may be more widespread in western North Carolina but vecause populations are small, localized, and mobile they may be difficult to find.
