|Scientific Name:||Diaemus youngi (Jentink, 1893)|
|Taxonomic Notes:||The name is sometimes spelled youngii, but youngi is the original spelling (Simmons 2005).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Barquez, R., Perez, S., Miller, B. & Diaz, M.|
This species is listed as Least Concern because, although it is seldom recorded, it has a relatively wide distribution, is tolerant of a broad range of habitats, has a presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

|Population:||This species is rare. Three specimens have been found in three localities to the Southern Cone. Little work has been done on this rare species, and therefore the range may be larger than what has been documented to date (Greenhall et al. 1983).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is found in forests and transition zones. This species has been found in moist tropical and dry forests, roosting in caves, tree hollows and on the edges of banana tree plantations (Elizondo 1999, Nowak 1999). It is hematophagous, meaning that is consumes blood. White-winged Vampire Bats feed mostly on blood from various bird species, including free-ranging poultry species (chickens, Guinea fowl and turkeys; Nowak 1999, Schutt et al. 1999).|
|Use and Trade:||This species is not used.|
|Major Threat(s):||This species can be confused with the Common Vampire Bat (D. rotundus) and be persecuted.|
|Conservation Actions:||In Mexico, this species is listed as subject to special protection under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.). It is found in protected areas.|
