Can Infiltrators be Indicators? Understanding Cuckoo Bumblebees

Cuckoo bumblebees are obligate parasites that must successfully invade and gain control of a host bumblebee colony to achieve reproductive success. As apex species, these cuckoos have been considered as potential indicator species of healthy bumblebee habitat for some time. However, our limited understanding of cuckoo bumblebee ecology makes it difficult to understand their full impact on host populations and the challenges they face as a group. In this talk, Sofia describes this fascinating host-parasite relationship and presents experiments she has conducted to unravel the complexities of the cuckoo bumblebee lifecycle.
