M. lucifugus is a 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 or M. lucifugus is not closely related to the big brown bat, which belongs to a different genus.
M. lucifugus mating system is polygynandrous, or promiscuous, and females give birth to one offspring annually. The offspring, called pups, are quickly weaned and reach adult size in some dimensions by three weeks old.
M.lucifugus has a mean lifespan of 6.5 years, though one individual in the wild reached 34 years old.
It is nocturnal, foraging for its insect prey at night and roosting in hollow trees or buildings during the day, among less common roost types.
M. lucifugus navigates and locates prey with percise echolocation.
Little Brown Myotis is a very small species, with individuals weighing 0.19 to 0.44 oz. with a total body length of 3.1 to 3.7 in. A variety of fur colors is possible, with pelage ranging from pale tan or reddish to dark brown and is very soft and fine.
M. lucifugus has a relatively short snout and a gently sloped forehead. Its skull length is 0.55 to 0.63 in.
The Little-brown bats braincase or skull appears nearly circular though somewhat flattened when viewed from the back. Its very thin pointy black tipped ears are 0.43 to 0.61 in. long.

It has few natural predators, but may be killed by raptors such as owls, as well as terrestrial predators such as raccoons. Other sources of mortality include diseases such as rabies and white-nose syndrome.
White-nose syndrome has been a significant cause of mortality for M. lucifugus since 2006, killing over one million little brown bats by 2011.
In the Northeastern United States, population loss has been extreme, with surveyed hibernacula (caves used for hibernation) averaging a population loss of 90%.
M. lucifugus is listed as Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future.
