Description

The velvety myotis is a small bat, although of average size for a myotine, with a total length of and weighing between . It has short, velvety, orange-brown fur over the whole of the body, which may fade to a brownish shade in preserved specimens. The ears and wing membranes are black and hairless. The ears are short and triangular, with a pointed tragus. Velvety myotis can be distinguished from all other New World members of the genus ''Myotis'' by the velvety nature of its fur, possession of larger

Biology

The velvety myotis feeds on insects, including beetles, bugs, moths, and flies, which it typically captures over water. They are generally found near rivers or over floodplains. They spend the day roosting in hollow trees, in burrows made by other animals, or beneath the thatched roofs of local buildings. They have often been recorded roosting together with

s, an unrelated species with similar habitat preferences. Little is known of their reproduction, although, like most bats, they apparently give birth to single offspring. Pregnant females have been captured between September and March.
