The insect known for having a queen is the ant. Ant colonies are highly structured societies where various castes, including workers, soldiers, and reproductive individuals, coexist to ensure survival and efficiency. The queen ant plays a crucial role, primarily responsible for reproduction within the colony. She can lay thousands of eggs and is essential for the colony's growth and continuity. Worker ants care for the queen's eggs, forage for food, and maintain the nest's infrastructure. This complex social structure enables ants to thrive in diverse environments and adapt to various challenges, demonstrating their success as social insects.
