Black-barred Brown moths have an hourglass-shaped black mark that is easy to see against the paler brown color of the wings. The shape's edges may appear rounded-off, giving it more the appearance of a figure eight in some individuals. A second dark mark beneath that black bar may also be present. Though the overall color of the moth is light or medium brown, a dark brown semi-circle sits at the outer edge of each forewing, very close to the tip. Caterpillars feed on Giant Ragweed, a species of the common allergen that can grow over 3 meters (10 feet) tall.
Look for adults from mid-summer through early autumn near riverbanks and stream edges where the host plant naturally grows.

Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
