Vespertilionidae

Vespertilionidae, commonly known as vesper or evening bats, is the largest family of bats, encompassing over 400 species worldwide. These bats are characterized by their relatively plain appearance, with variations in size and coloration. They are insectivores, mainly feeding on moths, beetles, and other small insects, which they catch in flight using echolocation. Vespertilionids are essential for controlling insect populations and maintaining ecological balance. Most are nocturnal, roosting in caves, trees, buildings, or under bridges during the day. They play a vital role in many ecosystems and are an important focus for conservation efforts.
