Pipistrelles are active between March and November (4). They hunt and eat insects on the wing in open spaces between vegetation (6). A variety of insects are taken, including small moths, midges and lacewings (2). Mating generally takes place in autumn at mating roosts, females then congregate in maternity roosts between May and August. One young is usually produced between June and mid-July, which will start to fly around three weeks later (2).
