G. bursarius has a wide range, extending from southern Manitoba and Saskatchewan in Canada south through the Great Plains of the United States to Texas and Louisiana, and east to Illinois, Indiana and parts of Ohio.
Habitat
G. bursarius occupies a wide variety of habitats, including prairies, grasslands, pastures, and agricultural fields, typically with well-drained soils suitable for burrowing.
Similar species
