Global Range: (200,000-2,500,000 square km (about 80,000-1,000,000 square miles)) Discover Life maps only about 39 actual localities, the range overall is an abbreviated version of many western species, notably not as far south as usual in California or into Canada. The limits of the range had not changed by the 1990s, and probably has not since. Records are scattered in Colorado and Utah into southern Idaho (Gooding, 1995, Minidoka 1995, Cassia 1999 Counties), southern Wyoming (as recently as 1990 in Sweetwater County), and eastern Nevada (Elko County in 1985). There was also a collection in Lander County, central Nevada in 1981. Farther west there are five mapped localities in Washington and Oregon, including Chelan County in 2006 and Harney County in 1989. There are also about ten localities (four 1990-1998) in the Sierra Nevada from Mineral to Inyo Counties, also one odd record from 1967 in Solano County, in California's central valley.
