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.
This first bat is a common pipistrelle, the clicking sounds it produces registering at 45khz, and we count them out as they loop over the garden and head off towards the fields.
On one recent outing near the Olympic Stadium, Ms. Oliver found about 10 pipistrelle bats, a common bat in the British Isles.
Instead we have this moronic inferno, a high-pitched fugue of endlessly self-referential squeaking, the sonar of a thousand bewildered but nonetheless blithely confident pipistrelle bats, all mothless.
The caves also contain one of the largest colonies of bats in the world: 11 species make their homes here, including western pipistrelle, pallid, lump-nosed, fringed myotis, and Mexican free-tailed bats.
The underground galleries hold ten species of wintering bat in reasonable numbers including the rare and Shreiber's bat Miniopterus schreibersi, lesser horseshoe bat Rhinolophus hipposideros (VU), long-fingered bat Myotis capaccinii (VU), greater mouse-eared bat M. myotis, Savi's pipistrelle Pipistrellus savii and western barbastelle Barbastella barbastellus (VU).
One near-endemic mammal occurs here, the disc-footed bat (Eudiscopus denticulus), and an endemic pipistrelle (Pipistrellus lophurus) (Table 1).
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).
The western pipistrelle bats Pipistrellus hesperus had largely abandoned their cave, except for one lone female who had several young clinging to her back.
Both these appear to be closely allied to the _pipistrelle_ of Europe, and are stated to have been found at Mussoorie and in Kashmir.
