What is the primary, non-negotiable dietary component for adult Bombus flavidus queens and males?

Answer

Nectar

The primary and non-negotiable substance that sustains the adult Yellowish Cuckoo Bumblebee, whether it is a queen or a male, is nectar. Nectar functions as the high-energy carbohydrate source required to fuel the significant muscular activity demanded by flight. This continuous energy supply is vital for the queen as she emerges from diapause, requiring high speed for travel between foraging sites and the immense energy expenditure associated with subduing a host queen to initiate her parasitic takeover. Because *B. flavidus* does not rear a worker caste, its energy needs are entirely self-serving for maintenance and dominance assertion, distinguishing its foraging focus from social bumble bees that must also gather protein sources.
