A desert species that is common in the Sonoran Desert of southwestern North America. These ants collect live and dead vegetation to use for the fungus gardens that they cultivate within their nests. This fungus is their primary food source. New colonies of this species can be founded haplometrotically or pleometrotically. Numerous studies have investigated fitness consequences and behavioral aspects of pleometrosis in Acromyrmex versicolor (e.g. Rissing et al. 2000, Cahan and Julian 1999, Hagen et al. 1988). Queens are polyandrous, which is an unusual trait in ants.
