Synonyms and other taxonomic changes Bombus occidentalis of western North America has often been treated as a subspecies of Bombus terricola but is now most often regarded as distinct. Explanation of Names Author: Kirby, 1837. Size queen: body length 17-19 mm
male: 13-17 mm
worker: 9-14 mm Identification see discoverlife.org for detailed descriptions of queen and male; worker resembles queen in general, but pubescence relatively longer Range northern and eastern North America? Most records from the Rocky Mountains of the USA mapped in the Williams et al. guide surely pertain to misidentified occidentalis. Food The Hosts section of its Discover Life species page lists known associations based on specimen records and images. Remarks
Declines of this species were first noted by John S. Ascher at Ithaca, New York, ca. 2001. In the 1990s this was one of the most common bumble bees in that region, but afterwards few individuals were detected. The species persists in relatively large numbers at some sites, especially in the northern portion of its range, but it has undoubtedly declined severely.
