BiologyRoosting in harems with one male and up to nine females and their young, the male must work to make his roost attractive to females, and then defend the area. Females may move between roosts, but males protect any females that are in his territory. The males often build tents in the tree-nests of ants and termites. It is not known how these are made, but from evidence in closely related species, it is likely that they excavate the inner regions of the nests using their teeth and claws, until a bell-shaped cavity remains (5). Females give birth to two litters each year, usually of a single pup in each. These pups are born with their eyes and ears closed and weigh 3.5 grams, after a pregnancy lasting 135 days (5). Their mothers feed them milk for the first 40 to 80 days of their life, and once weaning has begun, the young bats will fly next to their mothers on foraging trips. They live for up to four years (5). This bat eats the fruit of up to 22 plant species, and plays an important role in seed dispersal and plant renewal, particularly in older forests (5). Individuals do not travel far to forage; females spend the entire night foraging without returning to the roost, whereas males make several trips in order to defend and improve their roost (6).
