Identification
This is a small (about 2.5–2.7 cm wingspan) dark red-brown or yellowish-brown moth. There is a black basal streak, short in some specimens but extending halfway across the wing in the fold in others. The most prominent markings are the contrasting white cubital and median veins, and to a lesser degree the anal and radial veins as well. For the most part this white scaling stops well short of the wing margin. The trailing edge of the forewing is usually pale yellow or buff. The hindwings are dark sooty brown or black. Sexes similar. The combination of small size, robust build, red-brown color and contrasting white cubital vein will usually identify this moth.{{cite web |author1=Anweiler, G.
