Conservation Status: Least Concern.


This free-tailed bat prefers warm climates and is most commonly found in northern South America, Central America, and the Caribbean Islands.  It is believed that several colonies that have been found roosting in buildings in the Florida Keys are members of this family.  This bat is about the same size as the Brazilian/Mexican free-tailed bat (Tadarida brasiliensis).  Molossus molossus has several guard hairs on the rump, but can be distinguished from other free-tailed bats with guard hairs by its smaller size and wrinkled lips.
