Little information is currently available on the biology of this newly discovered bat. However, male Griffin’s leaf-nosed bats have been recorded in breeding condition in August at Chu Mom Ray National Park (1).
In general, other members of the Hipposideros genus roost in hollow trees, caves or buildings. Some species are gregarious, occurring in large colonies, but others may be found alone or in small groups. Like other Hipposideros species, Griffin’s leaf-nosed bat is likely to fly lower than most bats, and to feed on a variety of insects, such as beetles, termites, cockroaches and cicadas (2) (3).
Unlike many other bats, which emit their echolocation calls from the mouth, members of the Hipposideridae family (the Old World leaf-nosed bats) keep their mouth closed during flight, instead emitting the ultrasonic calls through their nostrils (2) (3). The calls are then focused by the complex structure of the noseleaf (3).
