| Pheidole portalensis|
Stefan Cover reports (personal communication) that “portalensis is an inhabitant of rock walls, where it nests in cracks, in elevations from 1100 to 1800 m. Colonies consist of several hundred ants or more. Minors forage singly on the rock faces, and recruit regularly to good food sources. Baiting is the only reliable way to locate colonies.” (Wilson 2003)
