The Fringed Myotis is identified by a conspicuous fringe of stiff hairs along the edge of its tail membrane, a feature visible when the bat is held in hand. It roosts in caves, mine shafts, and buildings in western North America, where large maternity colonies of hundreds to thousands may gather. The fringed membrane may improve aerodynamic maneuverability during hunting.
