The Spotted Bat is one of the few bats with a call audible to humans, an insect-like, high-pitched metallic click. It inhabits western North American deserts but was not known from Washington until 1991 because of its apparent rarity, its selection of high, sheer cliffs for roosting, and its high altitude foraging. Its presence is most dependent on the availability of high, sheer cliffs, but it forages over a wide variety of habitats adjacent to cliffs.

Range limits were drawn to include the deepest canyons and steep cliffs along the Okanogan River, the Columbia River, the Dry Falls canyon, and Moses Coulee. The steppe zones within its range limits were core and the Ponderosa Pine zone was peripheral. All habitats except closed forest and high to mid-density development were good. Future surveys are likely to show that this bat is more widespread in the Columbia Basin than indicated.
