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.
