According to the literature, Myotis laniger is slightly larger than Myotis laniger, but it is not easily separated in the field identification. Its body size overlaps with the South China Myotis bat. Phylogenetic relationships indicate that it is closely related to Myotis macrotarsus (<M. macrotarsus) and Myotis micropes (<M. hasseltii). It can live in caves, sewers, tunnels, buildings and under Bridges, and occasionally in leaves. Knot small groups, occasionally large groups (up to a thousand or more). Likes to be out on the water.
