Pipistrelle bats have tiny bodies with short hind legs and short, wide ears.
Pipistrelle bats are the most common species found in the UK and are also found across Europe, North Africa and Asia.
Bat’s mate in Autumn, just before hibernation, but the females egg cells are not fertilised until the spring. (Known as delayed implantation).
Once the embryo starts to grow gestation is between 6 and 7 weeks with usually just one baby being born in the summer.
Baby bats are tiny, blind for about a week and hairless. They rely on warmth for growth and development.
The young bat lives on its mother’s back – and is feed solely on her milk – until it can fly and hunt for itself; usually between three and six weeks.
Bats can live for up to 16 years.
Bats are the only mammals in the world capable of natural flight.
Bats live together in colonies. During the summer these are typically in trees, buildings that are accessible through gaps – they only require a space of 13mm to gain access through - or the eaves or rock crevices.
Pipistrelle bats hibernate in the winter; they gradually stop feeding and find themselves a suitable spot to hibernate – usually in crevices in buildings and trees.
Bats feed off lacewings, small moths, mosquitoes and midges and search for these over water, woodland, marshes and even urban areas.
Bats usually emerge from their roost shortly after sunset and spend the night foraging for food.
Bats do not damage to buildings that they roost in – other than the mess their droppings cause.
Bats are not aggressive, although like any wild animal, they may bite to defend themselves if handled.
It is important to note that in some countries Bats and their roosts are protected by law and it is an offence to damage, destroy or block access to their roosts.
