Hodgson's bat, also called the copper-winged bat or black-and-orange myotis, is a vesper bat distinguished from most other bats in its range by its yellowish colouring. Head and body length is 4.3–5.7 cm, the tail 3.6–5.6 cm and the forearm 4.3–5.2 cm, and it weighs about 15 g. It favours mountain forests and is found from Afghanistan to Taiwan, including Vietnam (Wikipedia, general species account).
It lives in upland and lowland primary and secondary forest at altitudes up to about 3,000 m, and roosts in caves and trees, sometimes buildings. It is an insectivore that finds prey by echolocation and catches it on the wing.
