Anochetus are presumably predators, using their snapping mandibles much like their larger relatives, Odontomachus. However, there are few direct observations. "A. mayri is found mostly in forests under stones, in moss on rocks or logs, in rotten twigs on the forest floor, or in larger bodies of rotten wood. The workers and queen feign death, and are difficult to see (Brown 1978)." There appear to be two distinct forms in the Atlantic lowlands of Costa Rica, one of which may be more arboreal (see below).
