New Mexico
Mackay and Mackay (2002) - This species commonly nests under stones, or under a log (1 nest); brood and reproductives were found in nests from May to August. This is one of the most common Crematogaster spp. in mesic and xeric sites in New Mexico. Workers are sometimes aggressive when the nest is disturbed. Foragers are often found on vegetation, especially cholla (Opuntia spp.). This species may be polygynous, as multiple, dealate females are often encountered in nests. Two colonies were nesting with Camponotus festinatus.
