The pocketed free-tailed bat is dark brown with ears that connect in the center. They get their name from a fold of skin that forms a pocket near their knees. This bat can be found roosting in rock crevices, small caves, and buildings within desert shrub and pine-oak forest habitats. Pocketed free-tail bats tend to have colonies of less than 100 individuals. Their range include the southwestern US and Mexico. This species eats mostly large moths but also beetles and other insects. Mothers have one pup per year.
