Evening bats (Family Vespertilionidae)

Evening bats or, perhaps more correctly, Vesper bats (Family
Vespertilionidae) are the largest and best-known family of bats.
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."

The family size range is from 3 to 13 cm in length, excluding the tail,
which is itself quite long in most species.
