  Pale Western Cutworm Moth, Pale Western Cutworm

  Agrotis orthogonia, the Pale Western Cutworm Moth, is a noctuid moth native to dry regions of western North America. Its larvae are subterranean cutworms that feed on the stems of wheat and other small grains just below the soil surface, causing significant agricultural damage during outbreaks. The species prefers loose, sandy, dry, or dusty soils and is particularly associated with wheat production systems. Adult moths emerge in late summer and fall, with most eggs hatching in late winter or early spring.
