Colonies
P. rugosus colonies can grow to have up to 15,000 workers.
Foraging Tactics
P. rugosus workers use group foraging tactics that involve the creation of permanent pathways (trunk trails). They also use pheromones trails to draw other workers to areas of food-availability.
Interspecies Interactions
Two other species of harvester ants, Pogonomyrmex anergismus and Pogonomyrmex colei, have no workers of their own. Instead, they live in the colonies of P. rugosus and Pogonomyrmex barbatus (red harvester ant) and enslave workers to raise reproductive males and females for them.
