POPULATION STATUS : Critically endangered (CR)


The Kolar leaf-nosed bat (Hipposideros hypophyllus ), or leafletted leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to India. Its natural habitats are subtropical or tropical dry forests and caves. It is found in only one cave in India, and its population is less than 200 individuals.


Its forearm is 38–49 mm (1.5–1.9 in) long.The fur on its back is variable in color, with some individuals’ hairs tipped with grayish-brown, while others’ hairs are tipped with rufous brown.Fur on the ventral surface is tipped in white or fulvous-white.Its nose-leaf has two supplementary leaflets that project from underneath the sides of the front nose-leaf.Its ears are 16.7–17.7 mm (0.66–0.70 in) long; its tail is 23.3–24.3 mm (0.92–0.96 in) long; its hind feet are 6.7–6.9 mm (0.26–0.27 in); its nose-leaf is 5.5–5.8 mm (0.22–0.23 in) wide.

Habits and Lifestyle

It echolocates at 103–105.3kHz.During the day, it roosts in caves.It has been documented sharing a roost site with several other species of bat, including Khajuria’s leaf-nosed bat (Hipposideros durgadasi ), fulvus roundleaf bat (Hipposideros fulvus ), and Schneider’s leaf-nosed bat (Hipposideros speoris ).It accumulates fat in the winter months, suggesting that it may use torpor in colder months.Pregnant and lactating females have been observed late in the summer.

LIFESTYLE : Terrestrial,



It is currently evaluated as critically endangered by the IUCN.The Kolar leaf-nosed bat is found in only one cave, and its population is less than 200 individuals.Its single cave is not on protected land, and the species itself is not protected by Indian law.Its habitat is under threat due to illegal granite mining.Granite miners have driven them out of at least two caves by setting fires; the fires make granite extraction easier.As reported in 2014, there was a temporary mining ban on the cave where this species is still found.Its critically endangered listing occurred in 2016; from 2004–2016, it was listed as endangered.From 2000–2004 it was listed as vulnerable, and from 1996–2000, it was listed as lower risk/near threatened.There are petitions to have the bat protected under the Indian Wildlife Protection Act, as all bats in India are considered vermin with the exception of two species.However, as of 2017, these petitions have not been successful
