Rafinesque's Big-eared Bat
Corynorhinus rafinesquii
Illinois - Endangered
Rafinesque’s big-eared bats roost in cave entrances, hollow trees, crevices behind bark, and dry leaves in the forest. They also live in abandoned buildings and under bridges and prefer to roost in partially lighted areas. They do not leave their roost until it is completely dark, forages for insects, and return to their roosts by sunrise. Their diet consists of insects - mosquitoes, beetle, and flies - with their favorite food being moths.
These bats are medium-sized with rabbit-like ears and a prominent nose. They are able to curl the ears backwards over the shoulder. During hibernation they coil their ears in front of their face and fold their wings.
