Little Brown Bat

Little Brown Myotis

Little Brown Bats have light brown fur, weigh less than half an ounce, and have a wingspan of 8-11 in. They are abundant across North America although they're present in lesser numbers in the southern states. They have an average lifespan of 6-7 years but can live much longer.

Little Brown Bats live in large colonies, leaving their roost at dusk and dawn to hunt for insects and spiders. Their high-pitched calls bounce off objects, helping them to find their prey. Summer roosts are tree cavities and buildings (often used by maternity colonies). They hibernate over the winter in caves or abandoned mines.

The females give birth to one offspring annually with the pups ready to fly and find their own food at 3 weeks.

Little Brown Bats fly and forage close to the surface of water and eat a great many aquatic insects such as Caddisflies, Mosquitoes, and Mayflies.

Did you know? Little Brown Bats can eat up to 1,000 small flying insects in under an hour.
