Vesper bats are the largest bat family with over 300 species, all of which can echolocate. They are widespread and found in every habitat except the cold polar regions. Those that live in temperate areas may migrate away or hibernate through the winter, when few insects are available to eat. All British bats are in this family apart from horseshoes.

Vesper bats (family Vespertilionidae), also known as evening bats or common bats, are the largest and best-known family of bats. They belong to the suborder Microchiroptera (microbats). Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the Latin word vespertilio ("bat"), from vesper, meaning "evening".
