It is one of the most common bat species in the [[British Isles]]. It is 3.5&ndash;4.5 cm long with a wingspan of 19–25 cm, with brown fur. It is common in [[woodland]] and [[farmland]] but is also found in towns, where it roosts in lofts and buildings. In 1999 the common pipistrelle was split into two species on the basis of different-frequency [[echolocation]] calls. The common pipistrelle uses a call of 45 kHz, while the [[soprano pipistrelle]] echo-locates at 55 kHz. Since then other differences, in appearance, [[habitat]] and food, have also been found. == Echolocation == The frequencies used by this bat species for echolocation lie between 45–76 kHz, have most energy at 47 kHz and have an average duration of 5.6 ms.<ref>Parsons S. and Jones G. 2000.
