Summary ⁷

The northern long-eared myotis (Myotis septentrionalis) is a small bat, typically 5-10 g and 84 mm in total length. The fur is dull brown on the dorsum and yellowish on the venter. Compared to other Myotis species, these bats have long ears with a relatively long tragus in each ear.

Description ⁸

Although the northern long-eared myotis is common and widespread, much remains to be learned about its roosting habits, reproduction, and longevity. This bat is known to hibernate in caves and mines and to roost under tree bark. It is one of the gleaners, plucking insects from the surfaces of leaves, branches, and the ground rather than taking them from the air in flight. Northern long-eared myotis hang from a perch to eat, which lets them take larger insects than they could if they ate on the wing.
