Nathusius's pipistrelles are similar in appearance to common pipistrelles, but they are slightly larger with longer fur.
The Maximun recorded age is 16 years.
Body length: 4.4-5.4cm, Wingspan: 22-25cm, Weight: 6-15g.
The fur is reddish-brown, often with grey tips.
Nathusius's pipistrelles inhabit Europe, but there are only a few records of their presence in England.
They are woodland bats and inhabit damp deciduous forests and dry pine forests.
They emerge to feed in early dusk, hunting small flying insects. They are rapid fliers, but are less agile than the common pipistrelle.
In the summer, they roost in bat boxes, hollow trees and sometimes buildings. In the winter they hibernate in caves, and crevices in walls and cliffs.
Males have mating territories, which may be occupied by a harem of 3-10 females. Nursery roosts are occupied from April/May and females give birth to two young in July. The young can fly after 4 weeks but are not weaned until 7-8 weeks.
Nathusius's pipistrelles are not listed by the IUCN list of threatened species.
