Natural History:

In Costa Rica this species prefers open dry habitats such as urban areas around San Jose and seasonally dry habitats of Guanacaste Province. I have records of the species from Santa Rosa National Park, Palo Verde, San Jose, and as far south as Quepos, but I never collected any Acromyrmex in the wet forest of the Osa Peninsula during extensive collecting there in the 1980's.

On the nature trail near the headquarters of Santa Rosa National Park I once observed workers carrying cut flower parts up a tree, suggesting that nests may occasionally be arboreal.

Queens multiply mate, and colonies are facultatively polygynous (Bekkevold et al. 1999).
