This magnet shows the white silhouette of a Brown Long-Eared Bat (Plecotus auritus) against navy blue fabric. A middle-sized bat by European standards, this bat lives in most parts of Eurasia. Diameter is 44mm (1.73").

Fun fact: The brown long-eared bat usually finds prey using its excellent hearing rather than echolocation. It feeds mostly on moths, and because some moth species have evolved the ability to detect bat echolocation calls and evade capture, this bat has adapted other hunting strategies.
