The pipistrelle bats ( Pipistrellus ) are a species of bat from the smooth-nosed family (Vespertilionidae). It is one of the taxonomically most controversial genera and is divided into several sub-genera. Worldwide there are around 35 species, including one extinct and five European.
description
As the name suggests, piped bats are among the smaller representatives of the smooth-nosed bats. They reach a head body length of 35 to 62 millimeters, a tail length of 25 to 50 millimeters and a weight of 3 to 20 grams. Their fur is usually dark brown or black, but there are also red-brown or gray representatives. The relatively short, wide ears are characteristic.
Way of life
Pipistrelle bats are found in a number of habitats, they can be found in open terrain, in forests and in the mountains. They use houses, hollow tree trunks, rock caves and much more as sleeping places. As a rule, they are less sociable than other smooth-nosed animals, and many species are solitary or can be found in small groups of up to 12 animals. They usually go looking for food early in the evening, sometimes in broad daylight. The species in cooler regions hibernate or migrate to warmer areas.
The pipettorbats' diet consists primarily of insects that they prey on in flight.
Once or twice a year, after a gestation period of 40 to 60 days, the female gives birth to one or two young, with twin births being more common than other bats. Females of many species form nurseries in which they retire for birth and rearing young.
The species
The systematics of the piped bat is still largely unclear. The approximately 35 species are divided into some sub-genera. The former subgenus Hypsugo , to which the native alpine bat also belongs, is now mostly listed as an independent genus. The subgenus Scotozous is also considered a separate genus today. The sub-genera Vespadelus and Neoromicia , which were sometimes also assigned to the pipistrelle or the broad-winged bats ( Eptesicus ), are now considered to be independent genera. The subgenus Perimyotis was divided into two genera Perimyotis and Parastrellus .
