Which other species is known as the Southern Cuckoo Bumblebee and is often confused with the Bombus vestalis?
Answer
Bombus bohemicus
The Bombus bohemicus, commonly referred to as the Southern Cuckoo Bumblebee, is a close relative of the Bombus vestalis. While they share similar parasitic behaviors, they target different host species, which leads to distinct ecological niches. Specifically, the Bombus bohemicus is known to mimic and parasitize the White-tailed Bumblebee, Bombus lucorum. Differentiating between these two parasitic species often requires understanding the host bee present in the environment; seeing a cuckoo bumblebee in an area dominated by Bombus lucorum suggests the presence of Bombus bohemicus, whereas an area dominated by Bombus terrestris points to Bombus vestalis.
