Pogonomyrmex rugosus (Rough Harvester Ant)

Pogonomyrmex rugosus is a trunk-trail forager. The workers stream out from the nest in long columns, often reusing the same pathways. The clear trail running from the center bottom of the photo is such a foraging trail - you can see how it is clear of debris. You can also see a few ants on the trail, at the center of the photo.
