Cutworms

The larvae or caterpillars of some moths are called cutworms (Agrotis, Amathes, Peridroma, Prodenia spp.) because of the manner in which they cut down young plants as they feed. The adults are night-flying moths which feed on nectar, if at all, and do no damage. There are many species of cutworms. While they all feed on plants by chewing, they vary as to damage done and host plants preferred. Generally they destroy more of the plant than they eat.
