LONG-EARED BAT

also called Lump-nosed Bat, or Big-eared Bat (Plecotus), any of five species of small, usually colony-dwelling bats of the family Vespertilionidae. Long-eared bats are found in the Old World and in North America. They are approximately 57 cm (23 inches) long without the 3.55.5-centimetre (1.42.2-inch) tail and weigh 520 g (1/62/3 ounce). They have soft, brown fur, and some species have glandular lumps on the muzzle. The ears, which may be 4 cm (1.6 inches) long, are folded when the bats rest. Long-eared bats fly slowly and frequently hover to pick insects from leaves or walls. They hibernate in winter.
