Catocala concumbens, the Sleepy or Pink Underwing (wingspan: 60-75mm), flies from the Yukon south to Alberta and in all provinces east: Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, to Prince Edward Island and Nova Scotia in Canada.
It has also been reported in District of Columbia, Illinois, Indiana, Maine, Maryland, Massachusetts, Nebraska, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Vermont, Virginia, West Virginia and Wisconsin.
The forewings are a silvery gray and have no streaks or dashes. The hindwing has an uninterrupted white fringe and there is a prothoracic brown collar clearly visible in this Lynn Scott photo.
At lights or on tree trunks, this species rests with wings folded and head down.
Catocala cara and C. amatrix are similar species, but concumbens lacks the checking of these two in the hindwing fringe and concumbens has a thicker and more even black median band that terminates before the inner margin.
This species comes readily to lights and to baits.

EGGS, CATERPILLARS, COCOONS AND PUPAE:
Eggs are deposited on tree bark in the fall and hatch the following spring.
Eggs can be overwintered in the fridge crisper and this species oviposits readily on the sides of brown paper bags.
Tiny hatchlings crawl like inchworms and are remarkably fast. They can escape through the smallest openings.
At maturity larvae will utilize a few strands of silk to fashion cocoons amongst leaf litter.
Adults emerge about 18-21 days later.

I am extremely grateful to Kirby Wolfe for his photographs of Catocala eggs. Concumbens females oviposit readily in inflated paper sanwich or grocery bags.
