Dorylus species have a constellation of behavioral and morphological features of "true amy ant", including two foremost attributes: group predation and nomadism (see Gotwald, 1995). Legionary behavior of Dorylus is found under stones and logs on the ground. One of the main prey items may be termites nesting in logs or under the ground.
