Charles Grove Young is the eponym for the species name youngi. However, in , Gerrit S. Miller placed it in a new genus, Diaemus. The outline of their wings is white, as well as the membrane between their second and third finger. The anterior surface of the tragus is hairy, and its outer margin is smooth, unlike that of the common vampire bat , which is serrated.

Charles Grove Young is the eponym for the species name youngi. However, in , Gerrit S. Miller placed it in a new genus, Diaemus. The outline of their wings is white, as well as the membrane between their second and third finger. The anterior surface of the tragus is hairy, and its outer margin is smooth, unlike that of the common vampire bat , which is serrated. Their thumb is much shorter than that of the common vampire bat. The calcar is absent. Their dental formula is 1.
The uropatagium and forearms are sparsely furred. Both males and females have cup-shaped scent glands located in their mouths. This may be because their foraging strategy requires more complex thought such as maintaining stealth than other species. Their eyes are also relatively large in relation to their body sizes.
These compounds in their saliva are especially effective on birds. Birds are their preferred prey source, but they will also prey on mammals such as goats and cattle. Females are polyestrous , capable of becoming pregnant multiple times a year.
They give birth to one pup at a time. While it is infrequently encountered, it has a broad distribution, and is tolerant of a variety of habitats. The population is assumed to be large. Captive populations can be supported with cow and chicken blood. Blood must be defibrinated to prevent clotting. They are social animals , and should be maintained in colonies. Their colonies have dominance hierarchies. Diaemus youngi. Downloaded on 16 September Jentink, FA Retrieved September 16, The eponym dictionary of mammals.
