Melanolophia carbonata Cassino & Swett, 1923
Wingspan 30-36 mm.
Forewing mottled brown or grayish, crossed by 3 or 4 wavy lines (the postmedial - PM - line is the most prominent of these lines, distinctly denticulate, and often the only one to cross the wing without fading); a dark blotch where the PM line meets the inner margin usually contains a curved whitish "V" reminiscent of a "flying seagull" - a good field mark when present.
Florida to Nova Scotia, west to Saskatchewan, south to Texas.
Larvae feed on leaves of birch, cherry, elm, maple, oak, pine.

Melanolophia signataria is extremely similar, but usually has more uniformly-colored wings (less mottling), and more objectively, typically has a more sinuous (somewhat "straighter") PM line, whereas canadaria usually has a noticeably denticulate PM line. Poorly-marked individuals may be difficult to distinguish.
