About Euxoa detersa Walker, 1856
Euxoa detersa, commonly known as the rubbed dart, sandhill cutworm, or sand cutworm, is a moth species belonging to the family Noctuidae. This species was first formally described by Francis Walker in 1856. It is distributed across North America, ranging from Newfoundland to North Carolina, westward to Nebraska, and northward to Alberta and the Northwest Territories. The wingspan of adult Euxoa detersa measures 30 to 35 mm. Adults are active in flight from July to October each year. This species produces one generation per year. The larvae of Euxoa detersa feed on corn, a variety of grasses, cranberry, saltwort, sea-rocket, many different garden crops, and commercial grains. The larvae build burrows and feed on the underground parts of their host plants. They are regarded as very destructive to crops grown in sandy soils.
