Pogonomyrmex rugosus (Rough Harvester Ant)

Pogonomyrmex rugosus nests usually have a large, circular area around them that is devoid of vegetation. This photo shows what happened to the vegetation. This plant is in the process of having all of its leaves chewed off by a recently established Pogonomyrmex nest. The ants will chew the leaves off, and as many of the stems as they can, until the plant dies.
