The black cutworm (BCW) is a migratory pest that cuts and feeds on early vegetative-stage corn. Black cutworm moths arrive in Iowa and other northern states with spring storms each year. These moths lay eggs in and around crop fields and emerging BCW larvae cut seedling corn. This pest is sporadic, making it essential to scout fields to determine if management is needed. Scouting for BCW larvae helps to determine if an insecticide application will be cost effective.
