In Ufeus satyricus'sagittarius sexual dimorphism is much more obvious than in the eastern subspecies. In the male the forewing is a shiny dark reddish brown with the maculation obscure except for a trace of pale streaks representing the reniform and orbicular spots and a hint of a darker postmedial line. The hindwing is dark fuscous, usually obscuring the postmedial line and discal spot. In the female the forewing is a paler reddish brown with a black streak between, above, or through the pale streaks representing the reniform and orbicular spots, the postmedial line is prominent, and usually there are numerous black streaks in the subterminal area. The hindwing is pale fuscous with the discal spot and postmedial line contrastingly darker. Unlike subspecies satyricus, the two sexes of sagittarius differ markedly in size with forewing length averaging 17. 6 mm (n=20) in males and 19.7 mm (n=20) in females. The two sexes of this subspecies frequently are sorted as two separate species in collections. Subspecies sagittarius occurs from the eastern edge of the Rocky Mountains in Alberta, Montana, and Colorado westward to the Pacific Coast.
