The long-eared Myotis has lighter, yellow fur on its back and 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 are typically located high in tree cavities, beneath the bark of dead or living trees, or in caves and old buildings. Pregnant females will roost in rock crevices, logs, or stumps. Moths are a staple in this species' diet.
