Description

The northern long-eared bat is a small bat, measuring an average of 8.6 cm (3.4 in) in total length, including a tail about 4 cm (1.6 in) long. Adults weigh between 5 and 8 g (0.18 and 0.28 oz). The fur and wing membranes are light brown in color, and the bat lacks the dark shoulder spots found in the closely related, and otherwise similar Keen's myotis. Compared to other Myotis species, these bats have long ears with a relatively long, pointed tragus; when folded forwards the ears extend well past the nose. They also have a longer tail and larger wing area than most comparably sized Myotis bats, giving them increased maneuvrability during slow flight.
