The White-winged vampire bat (Diaemus youngi), is a species of vampire bat, is the only member of the genus Diaemus. It is found from Mexico to southern Argentina and is present on the islands of Trinidad and Margarita. In Trinidad, up to 30 Diaemus bats were found in a hollow immortelle tree and one was found in a well-lit cave, along with the common vampire bat (Desmodus rotundus) and greater sac-winged bat (Saccopteryx bilineata). Flying individuals are easily identified by their white wingtips. This bat carries disease, including rabies in Trinidad.
