Description

Adults are pale-green, wedge-shaped, winged insects about 3 mm long with piercing and sucking mouth parts. Adults are broadest towards the head, the body tapering evenly to the wing tips. They have a row of six rounded, white spots behind their head. Nymphs are smaller than adults and are wingless.
