Snowy-veined Apamea Moth
Apamea niveivenosa, known as the snowy-veined apamea, is a noctuid native to northern North America. The was first described by Grote in 1879. Its larvae are subterranean cutworms that feed on grasses and have been documented as pests of grain crops in interior North America. The species occurs across Canada and extends south to California.
