The little free-tailed bat is one of the smallest species in the genus Mops, and a total body length is measured from 54 to 102 mm.

[4] This species shows great morphological variations in wing and pelage colors resulted in different taxonomic designations depending on its distributional ranges.

[5] These bats are found in savannas of Sudan, Guinea, and Zambia, in the Cape Macchia Zone, and more arid countries in the north.

Coleoptera (beetles), Hemiptera (true bugs) and Lepidoptera (moths and butterflies) are major prey for this species.

For instance, a population found in Amani, Tanzania, mainly feeds on Blattodea (cockroaches) with Hemiptera as the only other order to account for more than 10% of the diet.
