Biology According to Stefan Cover (personal communication), diversipilosa ^HNS is common at mid-elevations (1050-1900 m), favoring oak-pine-juniper forests, especially those in creek valleys, where it nests under rocks and in open soil. Colonies have single queens and large populations, which can exceed 1000 workers. Seed caches have been found in some nests.
