Overview
Extracted from Jonathan Koch, James Strange,Paul Williams.2012. Bumble Bees of the Western United States. A product of the U.S. Forest Service and the Pollinator Partnership with funding from the National Fish and Wildlife Foundation

Status: Common

Select food plant genera: Epilobium, Vicia, Trifolium, Penstemon, Geranium, Lathyrus

Tongue Length: Long

Distribution: Pacific coastline west to the Colorado Rocky Mountains, associated primarily with high elevations in the Intermountain West; dark form (B. flavifrons dimidiatus) found in western portions of the range; red form (B. flavifrons flavifrons) in eastern portions of the range

Can be confused with B. centralis and B. sitkensis

Females (queens and workers, colors refer to ‘hair’)

Thorax with black and yellow hair intermixed especially anteriorly, T1-2 yellow at least apicolaterally, T3-4 red or black, T5 black sometimes with yellow apically.

Mid leg basitarsus with the distal posterior corner rounded. Cheek length longer than broad. Hair of the face and top of head with black and yellow intermixed. On the side of the thorax, the lower anterior surface with long yellow hairs, corbicular fringes black with red admixture along posterior margin. Hair length long and uneven.

Extracted from: Laverty T.M., & Harder L.D., (1988). The Bumble Bees of Eastern Canada. Can. Ent. 120: 965-987.

Description. Body size of all castes medium. Head elongate, malar space about 1.5 times longer than broad. Colour pattern as in Figure 7; no variation in colour pattern recorded for eastern Canada.


Identification
Extracted from Bumble Bees and Cuckoo Bumble Bees of California by Thorp, R. (1983).

Discussion. B. flavifrons belongs to the group of species which includes B. caliginosus, centralis, and varufykeiy and is most closely related to B. centralis. In California, it differs from centralis in having predominantly black instead of red hair on metasomal tergites 3 and 4, and in the admixture of black to the yellow hair on the anterior scutum. Males of B. flavifrons in California may have yellow hairs on much of tergites 3 and 4, thus resembling faded males of centralis or yellow males of vandykei. They can be separated from both by the presence of some black hairs basally on tergites 3 and 4. The California color form ("cHmidiatus" populations) exhibits some color variation to include females with some reddish hair apically on tergites 3 and 4, thus tending toward the nominate color form. The males exhibit more variation, especially in the amount of yellow hair on tergites 3 and 4. Nests of the nominate color form in Alberta, Canada, are discussed by Hobbs (1967b).
