Vesper Bat

High Quality Content by WIKIPEDIA articles! Evening bats or, perhaps more correctly, Vesper bats (family Vespertilionidae) are the largest and best-known family of bats. They belong to the suborder Microchiroptera (microbats). There are over three hundred species distributed all over the world, on every continent except Antarctica. Sometimes the family is called "common bats." It owes its name to the latin word vesper, meaning "evening."
