Explanation of Names
BRUMOSA: from the Latin "bruma" (winter)
"brume" [n.] - fog or mist; "brumous" [a.] - characterized by fog or mist
perhaps a reference to the patchy and indistinct markings on the forewing, reminiscent of fog or mist
Wingspan about 38 mm.
Adult: forewing a patchy mixture of black, gray, and white, with no sharply-defined markings; basal, anal, orbicular-reniform, and subterminal dashes present but diffuse and indistinct, showing little contrast against dark ground color of wing; postmedial line double, whitish, faint; orbicular spot oval, whitish, with dark dot in center; overall appearance seems mottled and diffuse, as though obscured by patches of fog. Thorax mottled dark gray; basal segments of abdomen brownish-orange.

New York to Florida, west through southern states to California, north at least to Utah.
Dry oak woodlands and barrens.
Larvae feed on leaves of oak.
This species is listed in collections in Quebec and Wisconsin, but there is no indication that the specimens were collected locally (A. brumosa is not on the list of Acronicta species from Canada here).
