white-winged vampire bat

The white-winged vampire bat (Diaemus youngi), a species of vampire bat, is the only member of the genus Diaemus. They are found from Mexico to northern Argentina and are present on the islands of Trinidad and Margarita. In Trinidad, up to thirty Diaemus bats were found in a hollow immortelle tree, and one was found in a well-lit cave, along with Desmodus rotundus and Saccopteryx bilineata. Flying individuals are easily identified by their white wingtips.
