We are all familiar with Bumble Bees, but did you realize that some Bombus species are actually nest parasites of other Bumble Bees? This rather disheveled looking bee is the Lemon Cuckoo Bumble Bee (Bombus (Psithyrus) citrinus) (a male), which is a parasite of the Common Eastern Bumble Bee (Bombus impatiens) and the Half-black Bumble Bee (Bombus vagans). After sneaking her way into the host colony, a female Lemon Cuckoo Bumble Bee dispatches the queen and takes control of the nest’s workers who soon begin to feed her own young until they reach maturity. Nature is incredible! Photographed in Easley, South Carolina.
