pipistrelle

However, while the many differences between these two species have only recently been acknowledged, both were originally named during the 1700s and 1800s: the 45 kHz pipistrelle is P. pipistellus (Schreber, 1774) while the 55 kHz pipistrelle is P. pygmaeus Leach, 1825.

Many people might immediately think of the two pipistrelle species dubbed informally the 45 and 55 kHz pipistrelles: in 1993 it was discovered that the ‘species’ Pipistrellus pipistrellus actually consisted of two distinct species, both of which differed in the echolocation frequencies of their calls, and which were later shown to differ in genetics, morphology and behaviour (Barlow et al. 1997, Davidson-Watts & Jones 2006).
