This North American bat has large ears and brownish-gray fur. It leaves its roost late at night to catch moths and other insects along forest edges and waterways.
The fur is brownish gray and may have a reddish hue on the back. The underside is lighter, and the large, long ears are a conspicuous feature of adults.
It leaves its roost several hours after dark to forage along forest edges and waterways. It catches insects in flight and can glean stationary prey from surfaces, with moths making up most of its diet.
