Habitat use, roost ecology and natural history for the species at global scale are poorly known. In Taiwan, the species has been known to roost in foliage of 35 plant species, mainly broad-leaved trees (e.g. Terminalia catapapa, Dimocarpus longan, Hibiscus tiliaceus and Swietenia mahagoni) and in buildings during breeding seasons (Chang 2007). Records are from small secondary forest fragments and settlements in rice paddy-dominated landscape in the lowland during breeding season. It has been recorded using nature caves and abandoned tunnels in mountain area with elevations over 1800 m as hibernacula in India (Chakravarty et al. pers. comm.) and in Taiwan (Heng-Chia Chang, pers. obs). In Pakistan, few individuals were captured in a mountainous landscape dominated by agriculture lands, forest patches and grassland in warm temperate zone (Mahmood-ul-Hassan and Salim 2015). In Taiwan, a well-studied maternity colony began to form in late March, and number peaked in May when pregnant females gave birth with one offspring during May to June. The bats left the maternity roost sites between mid-August and early October for hibernation sites (Shen and Lee 2000). The species is reported mainly feeding on small flying insects, including coleopterans, lepidopterans, dipterans, hemipterans (Yang 1996) and foraging in rice paddy (Ying-Yi Ho, unpubl. data) and riparian grassland (Joe Chun-Chia Huang, pers. obs.) in the lowland.

The species has a rather wide distribution from Afghanistan to Taiwan. Bates and Harrison (1997) and Mandal et al. (2000) report the species from Afghanistan, India (Jammu and Kashmir, Himachal Pradesh, Punjab, Maharashtra, Uttar Pradesh, Bihar, West Bengal, Sikkim, Assam, Meghalaya and Karnataka). It occurs also in Nepal (Mahalaxmi and Dhaulagiri), Pakistan, China (Tibet and Jianxi) and Taiwan. The species has one record from northern Vietnam (Csorba et al. 2014, Mahmood-ul-Hassan and Salim 2015). Earlier records of the species from the Laos, Philippines, Indonesia, North and South Korea, Tsushima Island (Japan) as well as China’s provinces of Fujian, Jilin, Shanghai and Sichuan are referable to other species (Csorba et al. 2014).

The species is listed as vulnerable in Taiwan (Cheng et al. 2017). There is no direct conservation assessment in the other countries within its distribution. In Taiwan, all known hibernacula are found in protected forest areas. The protection of roosts and foraging habitats is important for this species. Since the population in Taiwan is migratory, the connectivity between its breeding habitats and winter hibernacula sites therefore is critical for this species as well. Studies on migratory movement and influences of pesticides to its survival are necessary. Further monitoring to understand the intensity of the incidences by wind turbines, vehicle collision and cat kill is also recommended.
