The Common Pipistrelle Bat is very widespread and common and can be found throughout England in woodlands, parks, mature gardens and in villages. It is also related to the Soprano Pipistrelle Bat and is almost identical in appearance. The body of the Common Pipistrelle is so light that it can weigh as little as ten paper clips.

The Common Pipistrelle Bat has sleek reddish brown fur on its back and yellow-brown fur on its underside. Its face and ears can be black or dark brown and its broad ears are black and triangular. Its wings are grey-black and quite narrow. The Common Pipistrelle is a very fast and jerky flier that likes to fly low while it zigzags through the air. It frequently changes its direction when in flight and  can often be seen near lamps or lighting in gardens where it hunts for insects. It can eat as many as three thousand gnats in one night.

Common Pipistrelle Bats prefer to roost in the roof spaces of modern buildings in small or large groups. They become quite noisy before emerging around half an hour after sunset. They also like to hibernate during the cold winter months in modern buildings as well as in trees.
