Crematogaster emeryana

This ant nests under stones or logs (or in logs), with brood present in April and July, and sexuals present in nests in July and August. This species appears to be polygynous, with up to 9 dealate females found in a single nest. One colony was nesting together with Lasius sp. and Tapinoma sessile. (Mackay and Mackay 2002)

Identification
