Biology

All known Azteca species are arboreal, nesting in living or dead wood, or external carton nests. Some species exhibit obligate associations with myrmecophytes, especially of the genus Cecropia (see Chapter 14 of The Ants). Feeding habits are generalized with foraging occurring both arboreally and on the ground.
