Until recently very little was known about this rare Seychelles bat. Colonies roost in caves and are thought to be divided into harem groups that consist of adult females and their young and are led by a single male (2). Unlike the African sheath-tailed bat C. afra (2), the Seychelles species hangs upside down from the cave ceiling to roost. Females give birth to their offspring during the rainy season that runs from November to December (2). These bats feed exclusively on insects (3) (7) (8).
