The rough-skin bat ( Pipistrellus nathusii ) belongs to the smooth-nosed family and is the largest bat species within its genus . The scientific species name honors the German breeding researcher Hermann Engelhard von Nathusius (1809–1879).
features
It reaches a maximum body size of 5 to 6 centimeters and a wingspan of up to 25 centimeters with a weight of 6 to 10 grams. In terms of its appearance, it is easy to confuse it with the other pipefish bats . A good distinguishing feature from the dwarf bat and mosquito bat is the 5th finger, which is usually longer in the rough-skin bat. It hunts its prey with echolocation sounds mostly between 37 and 41 kHz, with simultaneous hunting of several individuals a little deeper between 30 and 37 kHz.
Habitat & Nutrition
It feeds on small insects that are usually caught along rows of trees, forest edges, over bodies of water or in settlement areas in parks and near street lamps.
Quarters
The summer roosts of the rough-skin bat are crevice roosts such as B. trunk cracks, tree hollows and crevices, but they can also be found on buildings such. B. behind wood paneling. In winter, the species often relies on piles of wood or tree hollows.
Occurrence
The rearing takes place in Northern and Eastern Europe. Over the winter it moves to Central and Southern Europe.
Systematics
The rough-skin bat belongs to the genus of pipistrelle bats ( Pipistrellus ), which includes around 35 species worldwide. In Europe there are four other species that Kuhl's pipistrelle ( Pipistrellus kuhlii ), the pipistrelle ( Pipistrellus pipistrellus ), the soprano pipistrelle ( Pipistrellus pygmaeus ) and the Madeira Pipistrelle ( Pipistrellus maderensis ).
threat
Like many other species of bats, the rough-skin bat is endangered by a lack of roosts or by loss of roost, for example through the destruction of old wood and alluvial forests through forestry measures. There is also a certain risk from measures to destroy insects and from wind turbines. On the other hand, an expansion of the population is to be observed in areas in northern Germany.
In the Red List of the FRG the species is classified as "G - endangered migratory animal species", in the Red List of the IUCN 2006 it is considered to be least concern (least concern).
