All ants you see at work, all that explore the environment, all that go to war (which is total and myrmicidal) are female. Adult male ants are pitiful creatures by comparison. They have wings and can fly, huge eyes and genitalia, and small brains. They do no work for their mother and sisters, and have only one function in life: to inseminate virgin queens from other colonies during nuptial flights.
At first, most serve as attendants of the queen mother and her brood, from eggs to larvae and through pupae to newly emerged adults. Next they engage more in nest repair and miscellaneous other internal tasks. Finally, they become prone to service outside the nest, from sentinel to forager, to guard, to warrior. In a nutshell and put more plainly, where humans send their young adults into battle, ants send their old ladies.
