Pheidole porcula

Near San Angelo, Texas, Stefan Cover (unpublished notes) found a nest in a grassy flat, in clayey soil beneath a rock. Moody and Francke (1982) found numerous colonies in western Texas at 100–1700 m, nesting variously under stones, logs, cow dung, and under wood and fragments of metal, as well as in open soil.
