Description
Adult Chlorochroa range in size from 8-19 mm long and are broadly oval in shape. They are green to brownish or almost black in colour, and have a pale red/yellow/whitish margin around the body excluding the head. For at least some species, colouration varies with latitude, being darker in the south and greener in the north. The scutellum is long and triangular, sometimes has three bumps along the base and usually the tip is paler than the rest. The forewing membrane is often translucent.Nymphal Chlorochroa are mostly black except for a yellow/white margin around the body excluding the head.
Different species of Chlorochroa look very similar. They are distinguished mainly by the shape of the male genitalia and, to a lesser extent, by their distributions.
