The spotted bat is easy to distinguish from other North American bats, with tremendous, pink ears and the namesake white dorsal spots that dot its black pelage. Spotted bats are found in arid landscapes, often in areas of juniper, sagebrush, and pine savannahs. This bat typically roosts and hibernates in the rock crevices of cliffs or caves. While generally considered solitary, small groups of spotted bats may cluster together during hibernation. This species feeds mostly on moths and beetles. Elusive, much is still unknown about the life history of the spotted bat.
