Other Common Names
The existing common name is not optimal as it better applies to Bombus ruderarius montanus Lepeletier, 1836, a subspecies or synonym of a common Old World species. Perhaps "Rocky Mountain Bumble Bee" would be better?
Synonyms and other taxonomic changes
Bombus appositus Cresson, 1878
Similar to Bombus borealis but in appositus the anterior of the scutum is usually noticeably paler than the posterio of the scutum. Unlike fervidus the facial hairs are extensively yellow. Beware of worn centralis in which T3-T4 can appear yellowish rather than red.
Western mountains, typically at higher elevations, at least in the southern part of its range.

Disjunct records from southern Arizona mapped as unverified data in the Williams et al. guide were long ago established to be definitely erroneous by R. W. Thorp.
