Jamie Kroll, a student in my biology class, interviews a territorial male Black-legged Meadow Katydid (Orchelimum nigripes) singing in a cattail marsh at Lambert Lake, close to College of DuPage in Glen Ellyn, IL. Stridulation is a courtship ritual among katydids; he is singing to attract a female for mating before they both die from the cold winter. He bites that annoying finger to defend his territory!
