The range of this bat covers the southwestern states and it is most commonly found where caves or abandoned mine tunnels are available (Alden et al. 1999). Other common habitats include a wide range of areas, such as coniferous forests, mixed forests, and deserts, to stream and river areas of native prairies (Tuttle 2003). They do not seem to prefer to use crevices in such sites and may occasionally inhabit old buildings. As these bats are found in a variety of settings, they appear to show no preferred type of plant association (Schmidly 1977). In the Trans-Pecos, this is probably the most distinctive bat of caves and mines (Davis and Schmidly 1994).
