😛 A chaste cuckoo bumblebee. My first encounter. As a parasite, it prefers the dark earth bumblebee as its host. It invades half-finished nests and lays its eggs there. This species has no workers. It lets other bumblebees care for its larvae. The name says it all. A very large, muscular bumblebee. It has to be that way to overcome the resistance inside the nest. It also has no “pockets” for collecting pollen. Because, as mentioned, the workers of the infested bumblebee species take care of that.
