Euxoa detersa, the rubbed dart, sandhill cutworm or sand cutworm, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. It is found in North America from Newfoundland to North Carolina, west to Nebraska, north to Alberta and the Northwest Territories.
The wingspan is 30–35 mm. Adults are on wing from July to October. There is one generation per year.
