A wasp's job in nature varies by species but generally includes pollination, hunting pests, and colony maintenance. Social wasps, like yellow jackets, have roles such as workers, drones, and queens. Workers forage for food, care for larvae, and protect the nest, while the queen lays eggs. Solitary wasps, on the other hand, hunt and provide food for their young without forming large colonies. Their roles contribute to maintaining ecological balance by controlling insect populations and assisting in plant pollination.
