Natterer’s bat is a medium-sized species. The ears are narrow, fairly long and slightly curved backwards at the tip. The inner lobe of the ear (the tragus) is long, narrow and sharply pointed. A characteristic feature of this species is a fringe of very stiff bristles along the trailing edge of its broad tail membrane. Its rather pinkish limbs give rise to its old name of ‘red-armed bat’. Natterer’s bats tend to forage in broad-leaved woodland and along tree-lined rivers and ponds.
