Vespertilionidae is the largest family of bats, often referred to as vesper bats or evening bats. These bats are found worldwide and exhibit a wide range of sizes, shapes, and behaviors. Most are insectivorous, feeding on insects they catch in flight. They typically have simple faces without elaborate noseleaves. Think of them as the everyman bats, diverse and found all over the globe, just doing their part to keep the insect population in check. π
