Locating and assessing populations of katydids
Forrest T. 2016. Locating and assessing populations of katydids
Collected specimens and acoustic recordings of several species of katydids (genera Amblycorypha and Scudderia) at Greenbrier, Purchase Knob, and Big Creek, looking at natural history and distribution of species best told apart by song. 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 were 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 in 2002/2003, including Sal Patch Gap, Cove Creek Gap, and a site in the Big Creek/Mt. Sterling area, which is probably the location where TH Hubbell collected S. septentrionalis more than 40 years ago. S. septentrionalis could not be located at Cove Creek Gap in 2003. S. septentrionalis may be more widespread in western North Carolina but because populations are small, localized, and mobile they may be difficult to find.
