Range: Holarctic. Central Alaska southeast through Canada south of the taiga; northern United States from central Washington south along Rocky Mountains to northern New Mexico; east to Illinois, Virginia, and Maryland.

Conservation: Not usually of concern, but isolated populations in plains and east of the Cascades should be conserved.

The Nature Conservancy Global Rank: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Management needs: Protect habitat of selected populations.
