 Northern long-eared bats are well-suited to foraging in the forest interior.Their echolocation calls have a classic frequency-modulated structure that allows these bats to navigate through cluttered environments, although they are shorter, quieter, and higher pitch (126 to 60 kHz) than those of other "Myotis" bats.Their diets are focused on moths, although they also eat beetles, flies, and other insects.
