The Dot-lined Angle Moth has a wingspan of about 1 inch. The forewing is speckled light yellow or grayish-brown with darker shading in the subterminal area. This moth is highly variable in coloration. Antemedial and median lines are brown and slightly wavy. The discal spot is an inconspicuous short dash. The terminal line is a series of black dashes. The hindwing is similarly colored but with a prominent black discal spot and almost always has an obvious point about mid-way along the outer margin. Sometimes this can be worn to be rounded in some older individuals.
