The long-legged myotis is one of the larger species in the Myotis genus. Its fur is a medium gray-brown color on the dorsal side, with whiter fur on the underside. The ears, face, and membranes are darker in color. Ears are large and pointed. True to its name, this species has relatively long legs that end in 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. Open areas and forest edges provide enough sun for the species to enjoy. Roosting sites include large caves and mines, with maternity roosts occurring beneath the bark of and within cavities of trees. They will also roost in rock crevices as well as among cliffs and buildings. Maternity roosts of several thousand long-legged myotis have been observed. Moths are a common insect in the long-legged myotis' diet. Within a single foraging period, lasting less than an hour, they can catch all of the prey they need for the night. They find their prey within forest clearings as well as target bodies of water and water tanks.
