Habitat for this species includes oak and ponderosa pine woodlands, in both highland and lowland areas, as well as in more open and arid regions. They make their roosts inside of large caves, mines, buildings, bridges, and dead or dying trees. The fringed myotis preys upon a variety of insects, such as moths and beetles. This species is known to be an agile flyer and has been observed flying nearly vertical.
