Bombus species on Locoweed, RMNP - Bombus appositus
Rocky Mountain National Park, Larimer County, Colorado, USA July 11, 2014 Size: BL ~ 21.5
This handsome Bombus was seen in Hidden Valley, elevation ~ 9200 feet, in Rocky Mountain National Park. The combination of black pleura,extensive rusty hairs on terga 2,3 and 4, and the black face with yellow hairs suggests a queen B. rufocinctus. Any help with its ID is much appreciated.
