The tricolored big-eared bat (Glyphonycteris sylvestris) is a bat species from South and Central America.


Individuals weigh 7–11 g (0.25–0.39 oz) and have forearm lengths of 37–42 mm (1.5–1.7 in). The fur on its back is long, woolly, and dark brown. Individual hairs are tricolored, with a dark basal band, lighter middle band, and dark distal band. Its dental formula is for a total of 34 teeth.[2]

Biology and ecology[edit]

It is likely insectivorous and frugivorous. It is nocturnal, roosting in sheltered places during the day such as hollow trees and caves. These roosts consist of a colonies of up to 75 individuals.[2]

Range and habitat[edit]

It is found in several countries in Central and South America. Its range includes: Bolivia, Brazil, Colombia, Costa Rica, French Guiana, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname, Trinidad and Tobago, and Venezuela. It is generally found at elevations lower than 800 m (2,600 ft) above sea level, but has been documented up to 1,100 m (3,600 ft).[1]


As of 2018, it is considered a least-concern species by the IUCN. It meets the criteria for this assessment because it has a wide geographic range, its population is presumably large, and it can persist in a variety of habitats.[1]
