Not all bumblebees gather pollen. Some, like this species, take over the nests of other bumblebee species and use their workers to provision the nests of their young. This is the most common eastern species of parasitic bumblebee, and it is actually becoming difficult to find. This is something local experts are monitoring to see if there might be issues causing the species to decline. (S. Droege, pers. comm.)
