Description Small bat with large ears, toe hairs that extend beyond the tips of the claws, bicolored belly fur, and two large, fleshy lumps on each side of the snout. Forearm 38-44mm. Most common in forested areas and along streams in the southeastern United States.

Warning Bats are susceptible to rabies, a serious viral disease that results in death if untreated. Rabid bats rarely attack humans or other animals, but bats found lying on the ground may be rabid. Never touch or pick up any bat. Stay away from any animal that seems to be acting strangely and report it to animal-control officers. If you are bitten by a possibly rabid animal, you must immediately consult a doctor for a series of injections; there is no cure once symptoms emerge.
