NatureServe Global Conservation Status Factors

Range Extent: 200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Range Extent Comments: This species ranges from northern Indiana to Montana south to central Texas and New Mexico (Ascher and Pickering 2014).  Krombein et al. (1979) indicate Minnesota to Montana south to Texas.  Actual records mapped by Ascher and Pickering (2014) are three from the Dakotas, seven from Nebraska (as recently as 1988), one in New Mexico, and two in Texas.  The New Mexico record in 1950 is actually one of the more recent (Ascher and Pickering 2014).  This was apparently a Great Plains species and it might that extends east in dry sandy savanna habitats in Indiana.  The 2010 Pennington County, South Dakota (Ascher and Pickering, 2014) and at least one at Indiana Dunes since 2003 (Grundel et al., 2011) are the only  records found from after the 1980s.

Number of Occurrences: 1 - 80
Number of Occurrences Comments: 2010 occurrence assumed extant. Also assumed that there are not hundreds of populations of this now very rarely collected bee.  However, it probably does occur in other preserves. Collected at Indiana Dunes during surveys conducted in 2003-2004 and 2010 (Grundel et al. 2011).

Number of Occurrences with Good Viability/Integrity: Unknown
Viability/Integrity Comments: The 2010 South Dakota site is a managed prairie remnant.  It is unknown if the management addresses the pollinator fauna. The Indiana sites is U.S. National Park Service land.

Overall Threat Impact: Unknown

Short-term Trend: Unknown
Short-term Trend Comments: Apparently only two collections in the last 25 years.

Long-term Trend: Decline of >80%
Long-term Trend Comments: Based on Discover life map and data, after 1991 vs. before 1991.  Most records were before 1950.

Intrinsic Vulnerability: Moderately vulnerable
Intrinsic Vulnerability Comments: Low fecundity.
