Soprano pipistrelles have recently been recognised as a species separate from common pipistrelles. These two can only be reliably told apart by the different frequencies of their echolocation calls: 55 kHz for the soprano rather than 45 kHz for the common. It has been suggested that British soprano pipistrelle roosts are more common in Scotland and parts of Ireland. In the August and September mating season, males defend their mating roosts from other males. Females visit the roosts, and one male can have a harem of up to 10 females.

The soprano pipistrelle (Pipistrellus pygmaeus) is a small bat that was only formally separated from the common pipistrelle (Pipistrellus pipistrellus) in 1999.
The two species were first distinguished on the basis of their different-frequency echolocation calls. The common pipistrelle uses a call of 45 kHz, while the soprano pipistrelle echolocates at 55 kHz. The two species are sometimes called the 45 kHz pipistrelle and the 55 kHz pipistrelle, or the bandit pipistrelle (common) and the brown pipistrelle (soprano). Since the two species were split, a number of other differences, in appearance, habitat and food, have also been discovered.
