| description |
A highly variable species. The male is boldly marked with black transverse bands between the eyes; the mesepisterna, thoracic sterna, and entire dorsum are black. The wings are also largely black, with the exceptions of yellow arcs behind the calli and the yellow commissure. The venter of the body is yellow, and the legs and face are tawny. The scutellum is sometimes spotted with yellow. Females vary greatly in color, ranging from: yellow with black stripes along the claval suture (phase A); semi-translucent yellow with black stripes (phase B); to entirely yellow (phase E) or entirely black; to variegated in yellow, ferruginous and black (phase H, phase I). Adult males are 4.2-4.8 mm long, while females are 4.5-5.3 mm. (Hamilton 1983)

| comments |
NOTE: Throughout much of their range, males of this species are easily recognized by their largely solid black wings with a thin yellow commissure. Females only exhibit the characteristic yellow clavus of Oncopsis flavidorsum if the rest of the wings are yellow, or solid black; this combination of characters is not found in flavidorsum. The frequency of the color phases of females also shows geographic variation (the frequencies listed on this page are representative of populations from New York to New Jersey). (Hamilton 1983) |
