The northern long-eared bat has dull brown fur with a slightly paler belly. True to its name, the northern long-eared bat has long ears that would extend well beyond the muzzle (nose) if laid flat. In addition to its ear length, the northern long-eared bat also has a long, pointed tragus. These two characters can help distinguish this species from little brown bats.
Northern long-eared bats are most active one to two hours after dusk and then again right before sunrise. Northern long-eared bats are capable of picking up insects like katydids off of vegetation. This feeding process is known as gleaning. Generally, northern long-eared bats begin feeding after dusk and often carry larger prey to their night roosts for consumption.

Little Brown Bat has glossy fur, smaller ears and tragus.
