Its color is typically bright green, with narrow yellow, orange, or reddish edges. It is a large, shield-shaped bug with an elongate, oval form and a length between 13–18 mm. It can be differentiated from the species Nezara by its black outermost three antennal segments. Its anterolateral (= in front and away from the middle) pronotal margin is rather straight and not strongly arced such as in Acrosternum pennsylvanicum.

Both adults and nymphs have large stink glands on the underside of the thorax extending more than half-way to the edge of the metapleuron. They discharge large amounts of this foul-smelling liquid when disturbed.this bug is from the order Hemiptera.
