Upon emerging from their cocoons, the " Psithyrus " males and females disperse and mate.
Among the few exceptions, which are indeed fed by adult hosts, are cuckoo bumblebees in the subgenus " Psithyrus ".
"Psithyrus " was historically considered a separate genus from " Bombus " due to the significant biological and morphological differences associated with its parasitic life cycle.
The males do not survive the winter but, like nonparasitic bumblebee queens, " Psithyrus " females find suitable locations to spend the winter and enter diapause after mating.
