This pale, gregarious bat usually forms clusters in day roosts in rock crevices or buildings, less often in a cave, tree hollow or mine. Emerging relatively late in the evening, it captures prey on the ground after an aerial search. It also takes prey in flight a few feet above ground vegetation. Food includes flightless arthropods, Jerusalem crickets, moths, beetles and small vertebrates.
Pups, usually twins, are born from May through June in maternity colonies that are generally small, but may include more than 200 adults. In west-central and southern Idaho, pallid bats are found in rocky river canyons and cliffs near water. The species ranges from British Columbia to Baja California and central Mexico.
