Which bumblebee species serves as the primary host for the Bombus vestalis parasite?
Answer
Bombus terrestris
The White-tailed Bumblebee, scientifically known as Bombus terrestris, acts as the primary host. The parasitic relationship relies on the Vestal Cuckoo finding this specific species because the host workers are genetically compatible enough to raise the parasitic brood, allowing the usurper to bypass the initial energetic costs of colony founding and resource gathering.
