Chlorochroa is a group of shield bugs, also called stink bugs, in the Pentatomidae family. There are more than 20 species, and they are found in Europe and North America. Adult bugs are 8–19 mm long and have a broadly oval shape. Their color can be green, brownish, or almost black, with a pale edge around the body (except on the head). The scutellum (the long triangular shield on the back) is narrow and usually lighter at the tip. The forewing membrane is often clear.

Nymphs (young bugs) are mostly black and also show the pale edge around the body. Many Chlorochroa look alike and are mainly told apart by the shape of the male genitalia and by where they are found.

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

The life cycle has three stages: egg, nymph, and adult. There are five nymphal instars (growth stages).
