Catocala badia coelebs (wingspan: 54-56mm) flies from Saskatchewan, Manitoba, Ontario, Quebec, (rare) east to New Brunswick, Nova Scotia and Prince Edward Island and south into Maine (possibly to Connecticut). Records also exist for Wisconsin, Michigan and Vermont.
The fringe is gray on the lower wing from the brief orange dash at the hindwing apex to the anal angle. Tim Dyson image.
There is also the form phoebe Hulst, 1885.

Moths come in to lights readily and also to bait.
The Catocala badia coelebs caterpillar shows a preference for Myrica gale (sweet gale).
Sweet gale is a deciduous, bushy shrub, growing to a heighth of four feet.
It is distinguished from other bog shrubs by its bluegreen leaf color, and unique leaf shape.
Leaves are toothed only at the end, which is rounded and wider than the leaf base.
Other reported hosts include Myrica pennsylvanica (Northern bayberry) and Comptonia peregrina (sweetfern).
Comptonia peregrina, courtesy of University of Connecticut Plant Database is depicted to the right.
The Catocala species generally spin a very flimsy and relatively large, loose cocoon, using a few strands of silk to bind leaf litter together. You can see the lighter silk, binding the dried sweetfern foliage, in the image below.

EGGS, CATERPILLARS, COCOONS AND PUPAE:
Eggs are deposited on tree bark in the fall and hatch the following spring.
I sent Tim Dyson a few eggs in the fall of 2004, and he rewarded me with what I believe are images of second (right), third and fourth (below) instar larvae.
