What evolutionary advantage does the cuckoo habit provide for female Bombus vestalis?

Answer

More energy for ovary development and finding host nests

By eliminating the need to build a nest, forage for food, and rear the first cohort of workers, the females reallocate their metabolic energy toward rapid ovary development and the successful location of a suitable host nest, allowing for greater reproductive efficiency.
