The long-eared myotis has lighter, yellow fur on its back with a grayish, pale underside. This bat's face, ears, and membranes are a darker, black color. True to its name, the long-eared myotis has long ears that end in slightly rounded tips. This species can be found in mixed coniferous forests, occurring at higher elevations within its southern range. Roosting sites occur high up in tree cavities and underneath the bark of dead or living trees, as well as within caves and old buildings. Pregnant females will roost within rock crevices, logs, or stumps. Moths are a staple in this species' diet.
