Amazon Ant

A slave-making ant that raids colonies of Formica ants to steal pupae, which then emerge as workers in the Polyergus colony. The sickle-shaped mandibles of Polyergus workers are adapted for combat but useless for foraging or nest maintenance. They depend entirely on their captive workers for food and brood care.
