The long-legged Myotis is one of the larger species in the Myotis genus. Its fur is a medium gray-brown on the dorsal side, with whiter fur on the underside. The ears, face, and membranes are dark. Ears are large and pointed. True to its name, this species has relatively long legs and comparatively small feet. The long-legged Myotis relies on wooded habitats, such as pinon-juniper and coniferous forests, at elevations of 4,000 to 9,000 feet. Roosting sites include large caves and abandoned mines, with maternity roosts commonly located beneath the bark of and inside cavities of trees. Long-legged Myotis also roost in rock crevices, among cliffs, and inside buildings. Maternity roosts of several thousand individuals have been observed. Moths are a common source of prey. Within a single foraging period, lasting less than an hour, individuals can catch all of the prey required for a night. Common foraging habitat includes forest clearings and bodies of water.
