The face is brown with a bold brown line(s) below the crown margin. The pronotum is mostly orange-brown, with a central white cruciate mark. The scutellum is bicolored, with the anterior half a brownish orange color and the posterior half a yellowish-white. The wings are a mixture of brown and golden yellow, with dark brown tips and some scattered white spots; the wing venation is dark brown. Males have yellowish valve and genital plates. The female pregenital sternite is white with a posterior dark brown medial area; the margins of this sternite are relatively straight. Adult males are 4.7-5.0 mm long, while females are 5.2-6.0 mm. (Barnett 1976).
Nymphs have a somewhat distinctive color pattern, being mostly bicolored with alternating white and brown. See here for images of nymphs: 1, 2. |
