Fascinating facts about the Lesser Short-nosed Fruit Bat
Weighing just 21 to 32 grams and measuring 70-127 mm long, the lesser short-nosed fruit bat, yet it roams from sea level up to 1,600 m across a continent-spanning range that includes Sri Lanka, Borneo, the Malay Peninsula and the Philippines. Its tiny body, brown-to-yellowish coat and bright orange or yellow collar let it blend into disturbed forest, mangroves and even beach vegetation, earning it a Least-Concern status.
A single male may roost with up to four females, and groups of females can swell to twenty individuals, but males also spend more than two months chewing leaf veins until they drop, then fashion the fallen fronds into a hanging shelter. This elaborate construction creates a hollow palm-fruit "cage" that the bats bite out to feed. Such cooperative shelter-building shows how tactile, visual and acoustic cues blend into a social system where both sexes help raise the young.
Gestation lasts about 120 days (3.5-4 months), after which a single newborn, estimated to weigh around 11 grams in a close relative, clings to its mother for over a month before being weaned at 40-45 days. Remarkably, male bats grow mammary glands equal in size to the female's, comprising more than 8 % of their body mass, and actively assist in nursing. This shared parental investment speeds growth: females become pregnant at six to eight months, while males reach sexual maturity only after a year, ensuring a steady flow of caregivers in each colony.
Feeding mainly on aromatic fruits such as mangoes, the bat extracts juice and soft pulp. Plants like bananas, avocados, dates, mangoes and peaches depend on this bat to spread their seeds across forests and farms. Yet the same habit labels the bat a crop pest, because its fruit-biting can damage orchards. This dual role highlights the delicate balance between ecosystem service and agricultural conflict.
Living up to 20-30 years, the lesser short-nosed fruit bat, giving it decades to contribute to forest regeneration and pollination cycles. Its long lifespan, combined with a stable, widely distributed population, means that even as habitats shrink, the species across islands from Borneo to the Andaman archipelago.

In the velvety blackness of a tropical night, the Lesser Short-nosed Fruit Bat unfurls its leathery wings, a whisper of movement as it takes to the air, its large eyes shining like lanterns as it navigates the dark canopy in search of sweet, succulent fruits. With each gentle beat of its wings, it dances through the shadows, a master of the nocturnal world, its delicate, almost translucent membranes allowing it to make the most of the faint moonlight that filters through the trees. As it flits from branch to branch, its high-pitched squeaks fill the air, a symphony of sound that echoes through the forest, a testament to the bat's remarkable ability to thrive in this secret, nocturnal realm.
