The short coat is close-fitting and shiny rusty brown over the entire body. With a maximum body length of 8.2 cm and a wingspan of 40 cm, it is between the size of its two relatives on the European continent. Very noticeable are the distinct glandular bulges in the corners of the mouth, which can be seen when the mouth is open.
As a typical tree bat, it inhabits old (woodpecker) cavities in trees in small groups, sometimes in larger groupings; however, it also uses buildings and sometimes nest boxes as roosts.
