The groups that ants live in are called colonies. A colony has a female ant called a queen which lays eggs. Those eggs will grow into more ants. Big colonies of ants have different kinds of ants that grow from the eggs. These are called different castes of ants. Some are "workers" which do jobs like carrying and digging, and "soldiers" which fight other animals. Worker and solider ants are females. Another type of ant are "drones" which are male ants.
