Aroga trialbamaculella, commonly known as the red-striped fireworm , is a small gelechiid moth native to the eastern and central United States. are active primarily from March to October, though records exist year-round.

Distinguished from similar small gelechiid moths by the specific pattern of white spotting on dark brown forewings: a small white spot on the fold before the middle, plus white spots at the and dorsally before the cilia. Larvae identifiable by the six darker yellow stripes on a pale yellowish or greenish yellow background and their characteristic leaf-skeletonizing with tube construction.
