The ants are 2–3 mm in size, and endemic to the northeastern United States and adjacent Canadian regions.[1] They do not forage for food, but instead 'scout workers' from the colony seek out nearby host colonies of ants, steal larvae and bring them back to their own colony. A small T. americanus colony could consist of a queen, two to five workers and thirty to sixty slaves.[2] In a study published in Animal Behaviour, researchers showed that T. americanus scouts target stronger colonies over weaker ones to steal larvae from.[2][3] It was formerly placed as the sole member of the genus Protomognathus.
