The Virginia Big-eared Bat (Corynorhinus townsendii virginianus) is a medium-sized bat 3½-4 inches long and weighing 9-12 grams. It has brown fur, a buff-colored underside, and there are two prominent lumps on the nose. The bats' large ears are over one inch (2.5 cm) long and connected by a low band across the forehead. This mammal roosts in caves in both winter and summer. Female Virginia Big-eared Bats form maternity colonies in caves where they rear their young. The bats forage for food in old fields, hay fields, and forested areas. Studies have shown that they travel up to 6.5 miles (10.5 km) from the cave to feed, and individuals often return to the same feeding area night after night. Like all bats they eat insects - particularly small moths.
