Common pipistrelle

Scientific name: Pipistrellus pipistrellus
The common pipistrelle is so small, it can fit into a matchbox! Despite its size, it can easily eat 3,000 insects a night - look for it flitting around the garden or a lit lamp post as it chases its prey.

When to see

April to October


The common pipistrelle is our smallest and most common bat. All UK bats are nocturnal, feeding on midges, moths and other flying insects that they find in the dark by using echolocation. Common pipistrelles feed in a wide range of habitats from grasslands to urban areas. They roost in tree holes, bat boxes and even the roof spaces of houses, often in small colonies. During the summer, females form maternity colonies and have just a single pup. Look out for common pipistrelles jerkily darting about as they hunt for insects in gardens, over wetlands, or around street lights at dusk. They hibernate over winter, usually between November and April, although they may come out to feed on warm days.

How to identify

The common pipistrelle has dark, golden-brown fur, a slightly paler underside and a dark mask around the face. Its flight is rapid with lots of twists and turns. The soprano pipistrelle is similar in appearance, so the two can be difficult to tell apart.


Widespread, but absent from Shetland and parts of Orkney.

Did you know?

It was only recently discovered that there are actually two species of pipistrelle bat - common and soprano - both originally grouped as Pipistrellus pipistrellus. They are distinguished by the different frequency of their echolocation calls.
