How does the Vestal Cuckoo strategy represent a form of social parasitism?

Answer

It exploits the host colony's resources and labor for its own reproduction

Social parasitism in the context of the Vestal Cuckoo Bumblebee is defined by the hijacking of a colony's established resources and workforce. Unlike standard bumblebee species that engage in a life cycle of labor-intensive nest construction and collective foraging to raise offspring, the cuckoo bee bypasses this entire process. By invading an existing nest, eliminating the original queen, and forcing the existing worker population to raise the cuckoo's own larvae, the parasite effectively outsources the massive nutritional and energy costs of reproduction to another species.
