description Black cutworm moth Overview
Black cutworm is the common name for Agrotis ipsilon, a noctuid moth with a wide distribution and strong migratory behavior. Its caterpillars feed on corn and many other broadleaf and grass crops, weeds, and turf, often cutting young plants at or just below the soil surface. The species matters to agriculture because larval feeding can remove seedlings and thin plant stands, while adult moths move over long distances.
