Conservation Status: Least Concern.


Common throughout its range, the pallid bat occurs in arid and semi-arid regions throughout northern Mexico and the western United States. Pallid bats eat beetles, grasshoppers, and moths, and they forage for slow-moving prey, such as scorpions, flightless arthropods, and sometimes lizards, at and near ground level. They use echolocation to detect prey, but also use their large ears to listen for prey movements. Pallid bats visit flowers in their hunt for insects, and are natural pollinators of several species of cactus.
