● Madera Canyon [Pinal Co], AZ USA [el. 1363 m / 4474 ft] view location in Google Maps » ● 11/03/10 8:48AM sunny, windy, air temp: 21°C / 70°F [IMAGE 2 of 2] Two Pogonomyrmex barbatus workers are seen here with the carcass of an Aphaenogaster ablisetosa harvester ant. The P. barbatus workers were engaged in what seemed a pointless tug-of-war, and gradually worked their way farther and farther from their own nest. It is possible that the Pogos were from different colonies, but it is doubtful, as no other nest was seen in the immediate vicinity. As with most Pogos, P. barbatus does scavenge for (and even prey upon) other insects as potential food sources.
