The Northern Long-eared Bat is federally listed as threatened in the United States due to catastrophic population declines caused by White-nose Syndrome, which has killed up to 99% of individuals in some hibernacula. It uses its long ears for gleaning insects from leaf surfaces as well as aerial hawking, giving it greater dietary flexibility than many bats. It roosts solitarily or in small groups beneath tree bark or in rock crevices.
