Cuckoo Bumble Bee on Common Milkweed - Bombus flavidus
NE of Long Lake, Florence County, Wisconsin, USA August 9, 2016
This cuckoo bumble bee was foraging on Common Milkweed (Asclepias syriaca) in a wildlife opening on Forest Service land. Could this be a Bombus insularis or B. variabilis? There are three more photos of this cooperative individual. Any identification help would be greatly appreciated. Thanks so much!
