The cave myotis varies in its appearance, depending on region, with species having paler brown fur in the east of their range and darker fur in the west. The face, ears, and wing membranes are a darker, dusky color. Prey for this species include moths, beetles, weevils, and other insects. The cave myotis can be found in forested habitat in a range of elevations. They will roost in caves, tunnels, buildings, and old mines. Populations of cave myotis have been observed to migrate south for the winter, while others will hibernate. Disturbances and the overgrowth of vegetation at roosting caves pose a threat to this species.
