Biology and Ecology

These bats live in large colonies, roosting on branches in mangrove forests (Rhizophoraceae family). They often travel long distances to forage for food. They forage at night and hang upside down on branches to sleep during the day. Their primary diet consists of fruits or nectar, such as rambutan, mangoes, and durian. They act as pollinators for many forest and fruit tree species.

The breeding season begins with gestation from October to November each year. Young are born between March and May annually. They typically give birth to one offspring per year.

Distribution

Found in southern Myanmar, Thailand, Indonesia, the Malay Peninsula, the Philippines, Java, Borneo, and in Vietnam, the species is quite common in U Minh, Kien Giang, and Doi Pagoda (Soc Trang).
