Its range extends south from New Mexico and Arizona into Mexico and Guatemala. Preferred habitat consists of dry forests and shrublands, ranging from ponderosa pine to mesquite. Southwestern myotis are often found in areas with rocky cliffs, and maternity colonies have been documented in hollow tree cavities. Its diet consists mostly of moths. Females give birth to a single pup each season.
