Rafinesque's Big-eared Bat, Plecotus rafinesquii
Scientific name: The genus name Plecotus is from two Greek words, plekos (to twist) and otus (ear), referring to this bat's habit of twisting its long ears almost in a spiral as it folds them down over its back when roosting. The species is the Latinized name of the eccentric French naturalist Constantine Rafinesque (1783 - 1840), who collected and described many species of flora and fauna of eastern North America. This species is also sometimes called the Eastern Big-eared Bat.
