Abstract

Stalk borer is native to Iowa and has only one generation per year. Adult stalk borers are grayish-brown moths with white spots along the forewing with a 1-inch wingspan. Adults emerge in early August and lay eggs in grasses and broadleaf weeds until October. Larvae hatch in late April and early May, or when 500 degree days (base 41°F) have accumulated.
