Ants are social insects that live in colonies. Some colonies only have a dozen ants in them while other colonies consist of up to one million ants in them. A large colony of ants consists mostly of female working ants, a few or one queen ant, which lays all the eggs, and usually some fertile male ants. All the ants work together for the betterment of the colony. Today, there are more than 12,500 species of ants that are classified.
