Many minor workers (the small black ants seen here) performed nest maintenance, and ventured forth on foraging trails - often returning with seeds or tiny flowers. A major worker is seen here as well, and appeared to be guarding the area around the nest entrance. - Pogolumina - Pogonomyrmex Harvester Ants of North America
