description Black cutworm Overview
The black cutworm, Agrotis ipsilon (Hufnagel, 1766), is a noctuid moth with a wide distribution in temperate regions. Its caterpillar is the damaging life stage: it feeds near the soil surface, attacks many crops and weeds, and can sever young corn seedlings at the stem. The species is therefore relevant to crop scouting and integrated pest management, while the adult moth feeds on nectar rather than cutting plants.
