Bats in Ireland

There are currently nine species of bats known to live and breed in Ireland. The most recent bat (and also our newest mammal), Nathusius’ pipistrelle, was discovered as recently as 1996.

With a wingspan of 12cm, Leisler’s bat is our biggest species weighing in at around 15 grams, less than a packet of crisps.

Our smallest bat, the pipistrelle, can eat around 3,500 small insects, such as midges, in one night. Bats make great guests at any barbecue!

The lesser horseshoe bat has not yet been recorded in Northern Ireland.
