The wingspan is 67–75 mm. Adults are on wing from July to September in one generation depending on the location.

The larvae feed on Betula papyrifera, Carya ovata, Populus alba, Populus balsamifera, Populus deltoides, Populus nigra, Populus tremuloides, Quercus species, and Salix species (including Salix eriocephala).


Catocala relicta elda, recorded from Oregon, was formerly considered a subspecies, but is now thought to be a synonym of Catocala relicta.
