Habitat and Ecology [top]

Habitat and Ecology: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, 1997). 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, 1997).
