A Pheidole rhea super major. This ant's head was so oversized that it seemed to have difficulty walking. They are much less common in the foraging columns than are the minor and major workers, presumably spending much of their time in the nest.

A Pheidole rhea nest (the small holes in the rock near my finger). The nests are usually in rock ledges, and often have large chaff piles outside of them. The ants often have distributed nests, with nest entrances scattered.
