Bechstein's bats are found in Europe. In the UK, they are mainly found in Dorset, Wiltshire, Hampshire, Sussex and Surrey.
They are predominantly woodland bats, preferring mixed woodlands, but also occupying pinewoods, gardens and parks.
Bechstein's bats leave the nest after nightfall. They are agile fliers, catching prey (moths, mosquitoes and beetles) in flight or from branches and off the ground.
They roost in tree holes and bat boxes during the summer, and in the winter they roost in cellars, tunnels and tree holes.
Bechstein's bats mate from autumn to spring, and occupy nursery roosts at the end of May. Females give birth at the end of June, and the young leave the nurseries at the end of August.
Bechstein's bats are classified as Vulnerable by the IUCN Red List
