| Rafinesque's big-eared bat inhabits forests and streamside areas throughout the southeastern United States. These agile flyers may be less frequently seen than some other bats because they leave their roosts only when it is completely dark, forage for insects in the dark, and return to their roosts before sunrise. Curiously, they prefer roosting in locations that have some amount of light. Their range overlaps that of several other forest-dwelling bats, such as the eastern pipistrelle, the big brown bat, and some members of the genus Myotis.
