Which bumblebee species acts as the exclusive host for the reproductive cycle of the Bombus vestalis?
Answer
Bombus terrestris
The survival and reproduction of the Bombus vestalis are entirely dependent on the presence of the Bombus terrestris, commonly known as the Common Carder Bee. The parasite has evolved a specific, obligate relationship where it must locate, infiltrate, and take over the nest of this particular host. Once inside, the female Bombus vestalis kills the resident queen and utilizes the existing worker force of the host colony to rear her own offspring. Because this relationship is so specific, the geographical range of the parasite is strictly limited to areas where the host maintains a healthy and stable population.
