The yuma myotis is a smaller bat with black to reddish-brown or light brown fur. Habitat for this species includes a variety of forested areas, such as juniper woodlands, thorny scrub, and deserts. Habitats with a water source are crucial. Roosts are commonly located in buildings and underneath bridges, however, yuma myotis will also roost in caves and mines. Maternity roosts have been found in tree cavities, where single males have been observed roosting in abandoned cliff swallow nests. The yuma myotis prefers foraging over water and will eat a variety of insects, such as moths, froghoppers, beetles, midges, mosquitos, and muscid flies. The loss of critical habitat and white-nose syndrome threaten the health of this species.
