Description: A typically dark species. Males have a black venter, dark brown to blackish face, paler yellowish-brown pronotum speckled with dark coloration, reddish brown scutellum, and contrasting yellow legs. The wings are ferruginous to dark brown with a pale spot along the apex of the commissure (inner edge of the wings). Females are quite variable, typical of members of Oncopsis. Color ranges from being completely dark with mostly black wings and a slightly paler clavus and thorax (phase A, 2%); black with hyaline, clear "windows" in the wings (phase B, 4%), entirely ferruginous or grey (phase H, 24%); yellowish wings with a contrasting black scutellum and face (phase G, 20%); yellowish, ferruginous with dark markings on the scutellum and a dark face (phase F, 41%); and mottled with ferruginous, brown, and black with a bright yellow venter (variations: phase C, 2%; phase D, 2%; phase E, 5%). Females have a very short, truncated pregenital sternite that is broadly excavated; this sternite shape is characteristic of this species. Adult males are 4.1-4.6 mm long, while females are 4.3-4.9 mm. The nymph of this species is entirely ferruginous. (Hamilton 1983)
Distribution in North Carolina

Out of State Record(s)
Distribution: Eastern United States and Southeastern Canada
Abundance: Uncommon to rare in the state with scattered records, only one of which is recent; probably more abundant in the mountains, but has also been found in multiple locations in the Piedmont and Coastal Plain (which is perhaps a result of the widespread distribution of the host plant), differing from the distributions of other Oncopsis that occur in the state.
