There are over 200 known species of army ant, divided into New World and Old World types. All are members of the true ant family Formicidae. New World army ants belong to the subfamily Ecitoninae. This subfamily is further broken into two groups, Cheliomyrmex and the Ecitonini. The Ecitonini group contains three genera, Neivamyrmex, Nomamyrmex, Labidus, and Eciton, the genus after which the group is named (Brady, 2003, Tree of Life). The most predominant species of Eciton is Eciton burchelli, whose common name is army ant and which is considered to be the archetypal species.  The Old World army ants are divided between the two subfamilies Aenictinae and Dorylinae.  The subfamily Aenictinae is made up of a single genus, Aenictus, that contains over 100 species of army ant.  The subfamily Dorylinae contains the aggressive driver ants. There are over 60 species known.  Army ant taxonomy remains ever-changing, and genetic analysis will continue to provide more information about the relatedness of the various species.

They live in these galleries and make excursions, most often at night, to hunt for food and water. These ants often set up satellite colonies inside homes from parent colonies located outside in a tree or landscape timber.
