Ecology

Myotis yumanensis is usually found in large mixed colonies together with the little brown bat (Hoffmann and Pattie 1968).

Reproductive Characteristics

This bat has only one young per year, and nothing is known about the mating and social system or natal sex ratio of this species. Mating is expected to be nonselective as in the little brown bat (Milligan 1993).
