It is a relatively large mouse-eared bat with a forearm length of 48–50 mm (1.9–2.0 in).
Its fur is short and velvety, with the fur on its back a gray, reddish-brown.
In contrast, its belly fur is off-white.[3]
Biology and ecology
It is insectivorous, consuming mostly beetles.[4]
During the day, individuals roost in caves, though they may also roost in human structures.[1]
As of 2019, it is evaluated as a least-concern species by the IUCN.
It meets the criteria for this classification because its extent of occurrence exceeds 20,000 km2 (7,700 sq mi); its population is presumably large; and it is unlikely to be experiencing rapid population decline.[1]
