Rhinolophus hipposideros, commonly known as the lesser horseshoe bat, is a small species of bat found across Europe and parts of Asia. It has distinctive horseshoe-shaped nose leaves that help it echolocate, allowing it to navigate and hunt for insects in the dark. This bat typically roosts in caves, old buildings, and tree hollows. The lesser horseshoe bat has a wingspan of about 25 to 30 centimeters and weighs around 5 to 10 grams. It primarily feeds on small flying insects, such as moths and beetles. This species is known for its social behavior, often roosting in groups, which helps them maintain warmth and protection from predators.
