The yuma Myotis is a smaller bat with black to reddish-brown or light brown fur. Habitat includes a variety of forested areas, thorny scrub, and deserts. Roosts are commonly located in buildings and underneath bridges, however, yuma Myotis also roosts in caves and abandoned mines. Maternity roosts have been found in tree cavities, and single males have been observed in abandoned cliff swallow nests. The yuma Myotis prefers to forage over water and will consume a variety of insects, including moths, froghoppers, beetles, midges, mosquitos, and muscid flies. The loss of critical habitat and the fungal disease white-nose syndrome threaten the health of this species.
