Alpine long-eared bat


The species is slightly larger than the common brown long-eared bat, which is also common in Central Europe. The snout-vent length is 46-55 mm, the forearm length 37-46 mm, the tail length 41-53 mm and the ear length 34-38 mm. The animals weight 6-10 g. The upperpart is light grey, light reddish brown or light brown-grey depending on the distribution, the underpart is yellowish white or greyish white to almost white. The head is predominantly whitish, a dark face marking extends from the corners of the mouth to in front of the eyes. Obviously characteristic for the species is a triangular, grey, hard field at the tip of the lower jaw.


Information on the habitat of the species is scarce. Like the other species of long-eared bats, it is likely to feed on insects and spiders collected from vegetation or the ground. The nursery roosts are often located in churches and contain up to 50 individuals. Winter habitats have not been found so far.
