The Little Brown Myotis has a lifespan of more than 10 years, and one was even captured at 31 years old!

In the summer, females rear the pups and live separately from the males. At the beginning of winter, the males and females reunite and hibernate together. They are endangered in Canada. This status is mainly due to a fungus that causes white-nose syndrome, a disease that grows in caves where bats hibernate.
