The Family Mormoopidae consists of mormoopid bats, commonly known as ghost-faced or mustached bats, found primarily in the tropical regions of the Americas, from Mexico to northern South America and the Caribbean. These bats are insectivorous, feeding mostly on flying insects using sophisticated echolocation calls. Mormoopid bats typically roost in large colonies within caves or hollow trees and are known for their leafless or wrinkled faces, which help channel sound during echolocation. They play an important ecological role in controlling insect populations and are notable for their adaptations to high-density roosting and long-distance flight.
