The fringed myotis (Myotis thysanodes) is a medium-sized brown myotis that is distinguished by a trim of fine hairs along the posterior edge of the uropatagium (skin between the last finger and ankle). This is a species of western North America, found in coniferous forests, pinyon-juniper woodlands, and various shrublands, roosting in cliffs, caves, mines, trees, and buildings. The fringed myotis is not a particularly common species and it has been difficult to understand much of its ecology.
