Great roundleaf bat, A species of Old world roundleaf bats
Also known as:
Great himalayan leaf-nosed bat
Scientific name: Hipposideros armiger
Genus: Old world roundleaf bats

Description

The great roundleaf bat is similar in appearance to the closely related intermediate roundleaf bat (H. larvatus). However, the great roundleaf bat is larger and possesses four, not three, lateral accessory leaflets on each side of the main noseleaf. This bat has a forearm length up to 9.8 cm , and weighs up to 60 g. After an experiment published by Kathryn Knight , in which they painted the accessory leaflets and the ears and videotaped, it was concluded that when they clicked the leaflets closed and their ears bent down. When listening to the clicking they opened their noseleaf and their ears.

Diet

The diet of great roundleaf bat is primarily insectivorous, favoring large, soft-bodied insects. It exhibits a marked preference for beetles and moths, but also feeds on spiders and centipedes. Rarely, it may consume small vertebrates.

Appearance

The great roundleaf bat is a medium-sized bat with a robust body covered in dense, dark brown fur. Its most distinguishable characteristic is its large, leaf-like nasal structure used for navigation. Moreover, it has large, broad wings stretching across its body. Sexual dimorphism is present in this species, with males being slightly larger than females.

Behavior

Great roundleaf bat displays echolocation precision in its foraging habits, feeding primarily on insects.

As nectar feeders, they also exhibit mutualistic behavior with flowering plants, aiding in pollination—exemplifying their vital role in maintaining local ecosystems.
