The Northern Myotis is a medium sized bat with dark brown fur on its back and paler fur on its underside. It is very similar in colour and size to the Little Brown Myotis, but the ears are longer (extend beyond the nose when pressed forward) and the tragus (fleshy projection which covers the entrance of the ear) is long, slender and pointed. Both the Northern Myotis and Little Brown Myotis sometimes use the same roosts or hibernacula and it is difficult to tell the species apart.

Wingspan: 23 to 27 cm (9 to 11 in), Weight: 6-9 g (0.2 to 0.3 oz).
