The African sheath-tailed bat weighs 10–12 grams (0.35–0.42 oz), with females slightly larger than males. Forearm lengths range from 45 to 55 millimetres (1.8 to 2.2 in). The fur is a deep brown, but slightly lighter on the belly. The nose is a pointed cone shape and the rhinarium is black and naked.[2] It is insectivorous, feeding on a range of insects, but particularly beetles and lepidopterans.[3] Feeding is strongly dependent on the season, with much greater feeding activity occurring during the rainy season.[3] It lives in caverns in groups exceeding 50,000. Within colonies, the social structure consists of harems of around 20 females being attended usually by a single male. While female juveniles sometimes remain within the cluster into which they were born, young males disperse and join bachelor clusters.[3]
