Native.  Comments. This widespread species apparently prefers open habitats with well-drained soil including dunes, beaches, limestone barrens, soybean fields, old fields, open gaps in spruce forest, riverbanks and on pavement (see references under 'distribution'). The specimens from groundhog burrows were probably overwintering there.
