To which specific subgenus does the Bombus vestalis belong?
Answer
Psithyrus
The subgenus Psithyrus is a distinct group within the bumblebee classification that encompasses all known social parasitic bumblebees. This grouping is defined by the shared evolutionary history of species that have abandoned the social behaviors of traditional bumblebees in favor of a parasitic life cycle. Members of this subgenus, including the Bombus vestalis, are unified by their specialized, non-foraging lifestyles and their reliance on host colonies for reproductive success.
