Typical small Pogonomyrmex californicus nest, with lens cover in the foreground for scale. The asymmetry of the nest mound is typical of their nests.

Pogonomyrmex californicus worker from Phoenix, Arizona. Note that the gaster on these ants is black, not red, as in many other populations of P. californicus. Like many other ants, it is a bad idea to rely just upon color when identifying ants.

Another Pogonomyrmex californicus nest, with a lens cap next to it for scale. This is a small nest. Again, note the asymmetry - almost all of the soil is excavated to one side.
