The nymph bat ( Myotis alcathoe ) is a bat species from the genus of mouse ears . It was only described as a separate species in 2001 on the basis of genetic analyzes and morphological characteristics . The nymph bat was first detected in Greece and Hungary by a research group led by Professor Otto von Helversen . Both their scientific and their German names go back to Greek mythology . The nymph Alcathoe , daughter of Minyas , was turned into bats by Dionysus, together with her sisters , as punishment for boycotting a festival held in honor of Dionysus. Professor Helversen chose this name because the species was found in an area that resembles the area in which the tragedy is said to have occurred due to remote gorges and woodland .
The first evidence of this species in Switzerland came in 2002 when it was caught in front of a cave in the Vaud Jura at an altitude of 1500 m above sea level. M. This species has also been found in France and Germany .
features
The nymph bat is very similar to the large whiskered bat ( Myotis brandtii ) and the small whiskered bat ( Myotis mystacinus ). However, it is somewhat smaller than the two bearded bat species and differs somewhat from them in terms of their teeth. Furthermore, the frequency of their ultrasound location calls is higher than any other species in their genus.
habitat
The nymph bat prefers natural, water-flowing areas with old mixed forest , as can be found in valleys or alluvial forests (swamp forests with tall trees).
distribution
The species has been found in Europe in Albania, Bulgaria, Germany, Sweden, France, Greece, Poland, Switzerland, Slovakia, Spain, Hungary, Great Britain and Turkey. The northernmost German find was made in the Kyffhäuser Mountains.
threat
Since the nymph bat is a relatively newly identified species and very little is known about its distribution, no classification in a hazard category has yet been established in Switzerland. However, it can be assumed that the nymph bat has been confused with the bearded bat and since these are classified as endangered, this also applies at least to the nymph bat. Above all, the dependency on old trees is a problem.
