One mound, one queen, one king
Termites are known for their social structure that includes several castes with different tasks, and all individuals are somehow involved in parental care. Some are born sterile, having lost the ability to reproduce so that they can concentrate on raising the queen’s offspring.
Termites live in mounds that they construct in wood or soil. These often very large colonies are built and maintained by workers, and are defended by soldiers. The workers and soldiers can be females or males, and all are wing-less and sterile. Only fertile males and the queen have wings.
The queen mates continuously, but has only one partner, the king, which always remains in the colony with the queen.
