Description

Adult Chlorochroa range in size from 8-19 mm long and are broadly oval in shape.[2] They are green to brownish or almost black in colour, and have a pale red/yellow/whitish margin around the body excluding the head.[2][4] For at least some species, colouration varies with latitude, being darker in the south and greener in the north.[2] The scutellum is long and triangular, sometimes has three bumps along the base and usually the tip is paler than the rest.[2][4] The forewing membrane is often translucent.[2][4]

Nymphal Chlorochroa are mostly black except (as in adults) for a yellow/white margin around the body excluding the head.[4]

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.[2]

Diet

Chlorochroa feed on a range of different plants including apple, cotton, grape, English holly, Himalayan blackberry, hawthorn, arborvitae, groundsel, clover, alfalfa and cocklebur.[4]

Life cycle

The life cycle consists of the three stages of egg, nymph and adult. There are five nymphal instars.[2]
