Taxonomic Notes: Earlier treated under genus Pipistrellus Kaup, 1829 (Ellerman and Morrison-Scott 1951; Corbet 1978; Koopman 1993, 1994; Bates and Harrison 1997) and Scotoecus Thomas, 1901 (Menu 1987), now treated as a distinct genus (Tate 1942; Corbet and Hill 1980, 1991, 1992; Hill and Harrison 1987; Roberts 1977, 1997) (Srinivasulu et al. in press).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Molur, S. & Srinivasulu, C.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species is endemic to South Asia and is presently known from Bangladesh (Dhaka and Rajshahi divisions) (Khan 2001, Srinivasulu and Srinivasulu 2005), India (Andhra Pradesh, Assam, Bihar, Goa, Gujarat, Haryana, Jammu and Kashmir, Jharkhand, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Manipur, Meghalaya, Mizoram, Nagaland, Orissa, Punjab, Rajasthan, Tamil Nadu, Tripura, Uttarakhand, Uttar Pradesh and West Bengal) and Pakistan (Punjab and Sind) (Das 2003, Vanitharani 2006, Korad et al. 2007, Molur et al. 2002, Srinivasulu et al. in press). It has been recorded from sea level to an elevation of 2,000 m asl. The extent of occurrence is greater than 20,000 km² and the area of occupancy is greater than 2,000 km² (Molur et al. 2002).
Countries occurrence:
Bangladesh; India (Andhra Pradesh, Assam, Bihar, Goa, Gujarat, Haryana, Jammu-Kashmir, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Meghalaya, Nagaland, Orissa, Punjab, Rajasthan, Tamil Nadu, Tripura, Uttaranchal, Uttar Pradesh, West Bengal); Pakistan

Population [top]

Population:This is a widespread and common species and the population seems to be stable and doing well (Molur et al. 2002).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in drier climes and near human habitations in both rural and urban landscapes. It roosts in cracks, crevices, holes in old temples, old disused buildings and tombs and in holes in large trees in colonies of 2-24 individuals. It is a late flyer, hunts close to its roosting site and flies steadily. Its diet varies seasonally feeding on beetles, moths, grasshoppers, crickets in winter, winged termites, beetles, moths, orthopterans, hymenopterans in summer and termites, beetles, moths, orthopterans and hymenopterans in monsoon and feeds on agriculturally important insect pests (Molur et al. 2002). This species seems to breed almost throughout the year (Bates and Harrison 1997).

Threats [top]

Major Threat(s): Overall there appear to be no major threats to this species. As this species feeds on agricultural pests its population might be declining in parts of its range because of the use of chemical pesticides (Molur et al. 2002).

Conservation Actions [top]

Conservation Actions: Although there are no direct conservation measures in place, the species has been recorded from protected areas in India such as Satpura National Park in Madhya Pradesh. Further studies are needed into the distribution, abundance, breeding biology, general ecology and effect of pesticide overuse on this species. Public awareness activities need to be taken up highlighting the importance of this species in the agricultural ecosystem as the controller of insect pests (Molur et al. 2002).
