Habitat and Ecology [top]

Habitat and Ecology:Same as most vespertilionids, this is an insectivorous bat. Despite its large distribution, its biology is poorly known, bat surveys show this species is associated to Andean forests over 1000 m (Barquez et al. 1999, Wilson 2008). In Colombia, it has been reported associated to oak forests (Mantilla-Meluk and Muñoz 2014). This species is known to form small colonies in hollow trees (Wilson 2008).

Threats [top]

Major Threat(s): There are no major threats to this species.

Conservation Actions [top]

Conservation Actions: This species shows a large latitudinal and elevational distribution, from southern Mexico to northern Argentina; at the several countries it occupies, it is found in a number of protected areas. However, at the higher elevations of the Andes, loss of native forests should be avoided as this species depends on those ecosystems.
