The Pallid Bat has yellow to brown fur on its back, white fur on its belly, a flat, pig-like nose, and a conspicuous skunky odor. It is the only species in the genus Antrozous and is found mostly in arid environments and grasslands from southern Canada to central Mexico and Cuba. The pallid bat roosts primarily in rock crevices, however, this species can also be found in hollow trees, buildings, and mines. Little is known about its migratory behavior, with some populations hibernating in deep crevices and others remaining active throughout the winter. In addition to echolocation, Pallid bats use their large ears to listen for prey, including scorpions, centipedes, and beetles, which it gleans directly from the ground. Pallid bats have also been observed drinking cactus nectar, a highly unusual behavior for primarily insectivorous species. Mothers typically give birth to twins.
