There are several types of insects that have a king. One type is the termite. Termites live in colonies that can have up to several million members. The colony is divided into three castes: the reproductives, soldiers, and workers. The reproductives are the king and queen who mate and produce eggs. The soldiers protect the colony from predators and enemies. The workers build the nest, care for the young, and gather food.
Another type of insect with a king is the ant. Ants also live in colonies that can be very large. Each colony has one or more queens whose job it is to lay eggs. The rest of the ants are divided into two groups: those that take care of the young (workers) and those that defend the colony (soldiers).
Some bees also have kings. In a bee colony, there is only one reproductive female called the queen. She mates with drones (male bees) from other colonies and lays all of the eggs for her own colony. The worker bees are sterile females that do everything else such as build honeycombs, store honey, and take care of larvae.
