Catocala cara, the Darling underwing, (wingspan: 70-85mm) flies from Quebec and Ontario south through Connecticut to Florida and west to Texas and Oklahoma and north to Minnesota, Wisconsin and Michigan.
It has also been reported in Arkansas, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Massachusetts, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Vermont, Virginia and West Virginia.
I suspect it also flies in District of Columbia.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:
Catocala cara are usually on the wing from June to late October. Ian Miller confirms an August 18, 2011, flight in Eau Claire County, Wisconsin.

Note the deep maroon almost purple cast to the forewings, mixed with a very pale green. These moths often hide in caves during the day.
The greenish cast is quite evident on the violet ground colour in the photo to the left, courtesy of Maurice Bottos of Windsor, Ontario.
Note the postmedian line is distinct only to the base of the elongate upper teeth. The am line is thin and scarcely visible as it approaches the inner margin.
The reniform spot is pale grey-green outlined with a suffuse grey-violet band, then often surrounded by scales with a pale green cast.
The subreniform spot is concolourous, open, and only faintly outlined.
The prothoracic collar is grey-violet. The thorax is a mousy grey-brown with dark markings near its juncture with the abdomen. See wing descriptions.
The hindwing bands are relatively evenly curved. The creamy-white hindwing fringe is heavily checked with black and grey along the veins.
The Catocala cara caterpillar shows a preference for Populus and Salix.
Larvae are a pale beige-grey. There are pronounced orange warts on the fifth and eighth abdominal segments, with a darker grey-brown "saddle" hosting the first set of warts.
The prolegs are noticeably larger on the fifth and sixth abdominal segments.

"In July, Frederic Paquet, one of our staff members, found two very interesting caterpillars that were obviously masters of camouflage, and completely new to me. I took one inside to my office after taking pictures to raise it and see what would come out of it. Unfortunately, it escaped from my last minute temporary set up the first night and was not seen again. I later found out through your web site that it was indeed a Catocala caterpillar. To my surprise, during the second week of August, a gorgeous Catocala cara suddenly appeared on my desk chair, in my office, one morning. Thus the fate of the caterpillar was solved."
Sometimes taking a caterpillar home and rearing it to adulthood is the only way to determine species. David is not the only one to have a caterpillar escape indoors! Catocala can slip through the narrowest of openings.
Ron Nelson, teamed with Gabriel Larrabee, sent me the images below of Catocala cara eggs, larvae on Quaking Aspen and pupa, from Milwaukee.
