Plecotus is a genus of bats commonly known as long-eared bats. They are characterized by their large ears, which can be longer than their bodies. These bats are primarily found in Europe, Asia, and North Africa, and they inhabit a variety of environments, including forests and grasslands. Long-eared bats are nocturnal and use echolocation to navigate and hunt for insects. They typically roost in tree hollows, buildings, or caves. There are several species within the Plecotus genus, each adapted to their specific habitats and climates.
