About

The little brown bat or little brown myotis is an endangered species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.

Fun Fact

Little brown bats can eat up to 1,200 mosquito-sized insects per hour in flight, but white-nose syndrome has killed over 90% of populations in eastern North America since 2006.
