Deciduous woods, esp. those near wet areas. Caterpillars feed primarily on Poplar sp. but also some other deciduous trees.
I’ve caught this at all three eastern Ontario sites I’ve mothed at, but it doesn’t seem to be common in the literature; BugGuide has only two photos, and Covell doesn’t mention it at all. Handfield, however, calls it common in the southern part of Quebec (Montreal and surrounds). I was unable to draw a range map for this species; it reaches as far north as through the southern Boreal, but I don’t know how far south it ranges. I suspect to, but not beyond, the Carolinian.
From comments in Handfield, I think the above photo to be a male, and the below to be a female. Note they both have the white line across the “collar”.
