Biology
Aput et al. (2019) assessed how prevelant introduced plant seeds were in the diet of this seed harvester. A field trial showed the ants foraged in two daily bouts (morning and evening), and introduced species made up a small percentage of the seeds they gathered. Pogonomyrmex carbonarius foragers showed a clear preference for the native grass Pappostipa speciosa (Trin. & Rupr.) in preference trials that included both native and introduced plant seeds.
