Bombus centralis in Colorado Springs. - female

Bombus centralis in Colorado Springs. - Female
Colorado Springs, Deerfield Hills (N38° 47.041' , W104° 44.930'), El Paso County, Colorado, USA
July 1, 2005
Size: L = 9 mm
Found on Coreopsis grandiflora in my garden. Ventral pollen on S1S2S3S4. Ranges from Rocky Mountains west to Pacific Coast from the foothills to montane elevations (6500-9000 ft).
P.A.Byron (1980) found B. centralis at elevations of 6500-9000 ft. Looks very similar to B. flavifrons which lives higher up to subalpine elevations in the Front Range of the Colorado Rockies. IMHO, the two bees are subspecies and should be renamed
Bombus flavifrons centralis and Bombus flavifrons flavifrons, respectively. The workers of the two subspecies vary in body length: L = 9-10 mm for B.f.centralis (Colorado Springs) and L = 11-12 mm for B.f.flavifrons (Victor; Twin-Lakes; Breckenridge).
