About: Bombus suckleyi

Bombus suckleyi is a species of bumblebee known commonly as Suckley's cuckoo bumblebee, named after biologist George Suckley. Suckley's bumble bee is a generalist pollinator and represents a rare group of obligate, parasitic bumble bees (cuckoo bumble bees). Suckley's bumble bee is a social-parasite because it invades the nests of the host bumble bees, including the western bumble bee (Bombus occidentalis), and relies on host species workers to provision its larvae. It is native to northwestern North America, including Alaska and parts of western and central Canada and the western United States.
