African long-eared bats ( Laephotis ) are a species of bat in the smooth-nosed family (Vespertilionidae). They occur in the east and south of Africa.

features

The species reach a head body length of 45 to 59 mm, a tail length of 35 to 47 mm and a forearm length of 32 to 38 mm. Small species such as the Botswana long-eared bat ( Laephotis botswanae ), weigh 4.5 to 6.8 g, while larger representatives such as the Angola-long-eared bat ( Laephotis angolensis ) and the De Winton's Long-eared Bat ( Laephotis wintoni ), an average of 7.7 weigh up to 9.6 g. The German trivial name refers to the 15 to 19 mm long ears that are not connected by a strip of skin on the head. The fur has a copper-brown to olive-brown color on top, the underside is brown or gray. In contrast to the slit noses (Nycteridae), the ears protrude laterally from the head. African long-eared bats have four upper and five lower molars in each half of their jaws. There are two upper incisors on each side .

Types and distribution

The following species belong to the African long-eared bats.

Way of life

Very little is known about the ecology of these bats. Mostly single animals, pairs or smaller groups were found under detached tree bark. The inhabited habitat varies between species. The Namibia long-eared bat ( Laephotis namibensis ) occurs in the Namib desert . Other species can be found in savannahs , scrublands or heathland . African long-eared bats hunt insects, the De Wintons long-eared bat catches e.g. B. moths and beetles .
