The dark free- tailed bat ( Mosia nigrescens ) is one of the smallest bats and the only species of the genus Mosia within the smooth-nosed free- tailed family .

description

This bat is closely related to the species of the genera Coleura and Emballonura , they are grouped together in the tribe Emballonurini . Mosia differs from the other two genera through a different structure of the muscles on the hyoid bone . It also has a narrower shape. Mosia nigrescens reaches a head-trunk length of 32 to 41 mm and a tail length of 7 to 12 mm. The weight of the species is 2.5 to 4.1 g. She has a brown fur.

distribution

The distribution area is in Southeast Asia and in the biogeographical region Australis . It ranges from Sulawesi to New Guinea to the Solomon Islands . The species occurs in different habitats such as forests, mangrove areas and cultivated landscapes.

Way of life

The resting places of this bat are in caves, crevices, house roofs or behind large palm leaves. In contrast to Emballonura , mixed groups with males and females often occur. Shortly before dusk they go in search of food and hunt various insects. Since the proportion of wingless ants is high, it is assumed that the bat stays on the ground more often. Generally one cub is born per litter.

Mosia nigrescens occurs frequently and is listed by the World Conservation Union (IUCN) as " Least Concern " .
