Little brown bat (Myotis lucifugus)

The little brown bat (Myotis lucifugus) is a species of microbat found throughout much of North America and parts of Europe. They are small bats, with a wingspan of around 9-11 inches and a weight of only 0.2-0.5 ounces.

Little brown bats are named for their brown fur, which can range in color from dark brown to a reddish-brown hue. They have large ears and a small, triangular face.

Little brown bats are insectivorous, feeding on a variety of insects such as moths, mosquitoes, and beetles. They are strong fliers and are able to navigate and hunt for prey using echolocation.


Little brown bats are social animals and often form large colonies in trees, caves, or man-made structures. They are known to hibernate in the winter months, often congregating in large groups in caves or mines.


Despite their small size, little brown bats play a crucial role in the ecosystem as they help to control pest populations. They are also important pollinators, as they can carry pollen on their fur while feeding on nectar-producing plants.


Unfortunately, little brown bats, along with many other bat species, are facing significant threats such as habitat loss and disease. It is important to protect and conserve these vital animals for the health of our ecosystems.
