Justification
Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, has a tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Major Threats
There are no overall major threats to this widespread and adaptable species. In South Asia, while the population is generally stable, this species is locally threatened by human interference to roosting sites due to tourism related developmental activities, loss of preferred roosting sites, persecution by humans by means of poisoning, fumigation activities and stoning, hunting for medicinal purposes and local consumption (Molur et al. 2002).

Conservation Actions
In South Asia, it is classified as a vermin under Schedule V of the Indian Wildlife (Protection) Act. It has been recorded from protected areas in India like Namdapha Biosphere in Arunachal Pradesh, Nagarhole Wildlife Sanctuary in Karnataka, Sambalpur Wildlife Sanctuary in Orissa, Indravathi National Park in Chattisgarh, Kanha National Park in Madhya Pradesh. Further studies are needed into the distribution, abundance, reproduction and ecology of this species. Populations of this species should be monitored to record changes in abundance and distribution. Awareness activities need to be taken up to mitigate threats to this species (Molur et al. 2002). In Southeast Asia the species has been recorded from many protected areas and no direct conservation measures are currently needed for the species as a whole.

Contents

Distribution

The distribution range includes Pakistan, India, Nepal, Assam, Myanmar, Indochina, and Java (Lekagul and McNeely, 1977).

Description

Size according to Lekagul and McNeely (1977) as FA = 75 to 85, TL = 10 to 18, HB = 95 to 120, EL = 18 to 24, HF = 19 to 24 and WT = 45 to 106 g[clarification needed]

Biology and Ecology

According to a study by Lekagul and McNeely (1977), this bat is a cave dweller and lives in cooler climate but also roosts in wells, mines and artificial caves. Its diet consists of fruit juice and nectar, but it has also been found feeding on mollusks.
