The soprano pipistrelle is a sibling of the common pipistrelle.
It differs from the common pipistrelle in that it is slightly smaller and thus represents the smallest Central European bat species. Also, its echolocation sounds are not at the usual 45 kHz, but have a final frequency of about 55 kHz.
