The term "vespertilian bat" refers to bats belonging to the family Vespertilionidae. These bats, also known as evening bats, are the most diverse and widespread family of bats globally. They are primarily insectivorous, feeding on insects caught in flight. Vespertilian bats generally have simple faces and lack prominent noseleaves. These are the quintessential bats, the most common type you're likely to encounter, quietly patrolling the night skies for insects. 🌃
