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. The larvae feed on corn, various grasses, cranberry, saltwort, sea-rocket, various garden crops and commercial grains. The larvae construct burrows to feed on underground portions of host plants. They are considered very destructive in fields planted in sandy soils. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rubbed Dart is recorded against all the insects logged in Point Pelee National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
