pogolumina > ● Madera Canyon [Pinal Co], AZ USA [el. 1363 m / 4474 ft] view location in Google Maps » ● 11/03/10 8:46AM sunny, windy, air temp: 21°C / 70°F [IMAGE 1 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.

pogolumina > ● Mission Espada, San Antonio [Bexar Co], TX USA ● 3/01/10 3:14PM sun/clouds, air temp: 15°C / 60°F [IMAGE 1 of 4] Late winter/early spring nest maintenance. These Pogonomyrmex barbatus workers were slowly bringing loads of sand/soil up from the depths of their nest. They appeared to be utilizing their psammophores in some cases, and their mandibles alone, in others - depending on the moisture content of the soil they were transporting. It had rained the day before these images were captured, and much of the soil was quite moist and clumped - allowing it to be easily picked up and carried in the mandibles of these workers (like a clump of sticky rice can be picked up with chopsticks).

pogolumina > ● approx. 15 miles SW of Sonora [Sutton Co], TX USA [el. 658 m / 2160 ft] ● 3/02/10 1:10PM sun/clouds, air temp: 14°C / 57°F Only a few P. barbatus workers were active on this cool, partly cloudy afternoon. This area was very damp after recent rains, and this worker can be seen to have water droplets clinging to her body as she emerges from the nest.
