The Serotine Bat is one of England’s largest bats and is considered to be quite rare. It can mainly be found in the south of England in open woodlands, parks and mature rural gardens. This bat is often associated with houses and buildings.

It has a black face and two short, rectangular-shaped ears. Its fur is dark brown on top and light brown underneath. Its wings are long, broad and pointed at the tips. It is a slow and fluttery flier that glides for short distances. This bat can sometimes be seen flying around street lights in urban areas hunting for insects and can eat larger insects such as cockchafers and hawkmoths.

Serotine bats prefer to roost and hibernate in old buildings, barns and outhouses where they can be heard squeaking quite loudly. They sometimes share roosts with other bat species such as the Pipistrelle and Noctule bats, as well as the Whiskered, the Brown and the Grey Long-eared Bats. Serotine Bats often leave their roosts just before sunset and return at dusk. They can also be very noisy before entering their roosting sites.
