Nathusius’ pipistrelle is a rare bat in the UK, though numbers have increased in recent years. It is a migratory species, and most bats are encountered in autumn, although some do remain all year and breed in the UK. It is similar in appearance but slightly larger than the much more commonly found Common and Soprana pipistrelles, and the fur on its back is longer, giving it a shaggier appearance. Nathusius’ pipistrelles are often found hunting insects over lakes, rivers, canals and other waterlogged areas, as well as in woodland rides and edges.
