Nathusius’ Pipistrelle

Wingspan: 22-25cm Weight: 6-15g Lifespan: max. 16 years

(Pipistrellus nathusii)


Identification: A very small bat but the largest of the UK pipistrelles with longer broader wings. The upper fur is reddish-brown and shaggy in appearance and the underparts are paler. The face and ears are dark and the nose is more prominent than other pipistrelles. General: A native species which likes to forage over freshwater or in woodland and farmland adjacent to water bodies. They feed mostly on very small insects such as mosquitoes and small moths. Mating takes place in the autumn and one or two pups are born in late spring in large maternal roosts and weaned after 6 weeks. Roosts are in tree hollows or old buildings and hibernacula are usually in tree holes or cracks in walls. Distribution - UK: The population has not been determined but thought to be a few thousand in England but significantly more in Northern Ireland. There are small populations in Wales and eastern Scotland and they are restricted to south and east England. Sonogram
