Family: Vespertilionidae, Vespertilionid Bats view all from this family



Description Small bat with yellowish- to grayish-brown pelage, and a somewhat paler belly. Dorsal hairs are tricolored, and membranes are dark brown. In winter, hibernating individuals sometimes collect droplets of moisture on them, given them a sparkling appearance. Forearm 31-35mm.


Dimensions 75-90mm, 33-45mm, 6-10g


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.


Habitat Forests & woodlands, Canyons & caves, Cities, suburbs & towns


Range Plains, Great Lakes, New England, Mid-Atlantic, Southeast, Florida, Texas, Eastern Canada


Discussion Also known as Tricolored Bat. Summer roosts are in and on buildings, under shutters, and in attics and lofts of barns. Hangs with a hunched posture while sleeping. Individuals swarm in late summer and early autumn, seeking mates before entering hibernating caves. Uses a variety of habitats, especially open pasture.
