Catocala cara is a large underwing. The hindwing fringe is off-white and heavily checked with black along the veins. The ground colour of the forewings is grayish-purple with gray-green mottling and sharply defined black postmedial and antemedial lines that extend from the costa downwards to mid-wing.
The undersides are not
nearly as spectacular. The apex of all wings is darker than that
of most other species. |

These moths seem to fly consistently with their legs apparently ready for landing.
