This species has been taken in wet pine-oak forest, also in a variety of habitats including desert scrub, dry forest, and ponderosa pines (Reid 2009). Day roosts have been reported, night roosts include buildings, mines, and caves (Barbour and Davis 1969). Activity usually begins 1 to 2 hours after sunset, later than most myotis bats. The food consists mainly of moths gleaned from tree trunks or walls of buildings. In Arizona, single young are born in late June or July (Warner 1982, Reid 2009).	There are no major threats throughout the species' range.	It is rare in Guatemala (known from one specimen), more common farther north in other places (Reid 2009), in USA, it is common in appropriate habitats (Wilson and Ruff 1999).	Unknown	This species occurs from Arizona and New Mexico (USA) to Jalisco and Veracruz (Mexico), and Guatemala (Simmons 2005). It occurs from lowlands to 2,200 m (Reid 2009).
