Ants come in many sizes but the queen ant in any colony is the largest of the group. She does no work at all, while the other ants clean and groom her throughout her life. However, she does the colony some service by reproducing thousands and thousands of eggs so that the colony remains populated with enough workers and fighters. Honeybees too display similar behaviour. Bees are social insects and live in colonies. A colony or hive contains only one large, egg-laying female called the queen, along with about 50,000 female workers who cannot lay eggs and a few hundred males called drones. The female bee fed on royal jelly grows up to be a queen. The natural food of bees includes nectar and pollen, but royal jelly is a substance secreted by workers and fed to the chosen larva when the new queen needs to be elected.
