Brown long-eared bat
|Brown long-eared bat|
| Plecotus auritus|
The brown long-eared bat or common long-eared bat (Plecotus auritus) is a small European bat. It has distinctive ears, long and with a distinctive fold. It is extremely similar to the much rarer grey long-eared bat which was only validated as a distinct species in the 1960s.
An adult brown long-eared bat has a body length of 4.5-4.8 cm, a tail of 4.1-4.6 cm, and a forearm length of 4-4.2 cm. The ears are 3.3-3.9 cm in length, and readily distinguish the long-eared bats from most other bat species.
They are relatively slow flyers compared to other bat species.
This species appears to prefer caves as roosting sites, but roosts in trees holes, buildings and bat boxes, as well. The roosts in trees may be close to the ground.
