About Myotis velifer (J.A.Allen, 1890)
This species, scientifically named Myotis velifer, is larger than most other bats in the Myotis group, with a forearm length ranging from 37 to 44 millimetres, which equals 1.5 to 1.7 inches. It is brown in color and has short ears. A bare patch of skin on its back sets it apart from other large Myotis bats. Males of this species are smaller than females. For habitat and distribution, it typically resides in caves, though it is also known to live in mines and buildings. The largest populations of this bat occur in southwest Kansas and Mexico. During winter hibernation, groups of over a thousand individuals have been observed roosting on cave ceilings.
