Northern flying squirrel records in Minnesota concentrate in the Arrowhead’s boreal forest, at Superior National Forest, the Boundary Waters Canoe Area Wilderness, and Voyageurs National Park. As a strictly nocturnal glider, the species is almost never seen in daylight, so most records trace back to nest-box surveys or chance flashlight encounters rather than casual sightings.

Reports show two modest peaks, in May and August, though with only 51 iNaturalist records against 164 from GBIF, most of the documentation likely comes from research trapping rather than public observation. NatureServe has not yet assigned the species a Minnesota rank.
