Appearance

''Piezodorus lituratus'' can reach a length of 10–13 millimetres . These large shieldbugs occur in two adult colour forms. In the spring when they emerge and mate they are predominantly green, while the new generation that appears in the late summer has purplish-red markings on the pronotum and Corium. In autumn they have much paler color, prior to the hibernation they may become darker, but after the hibernation they are bright green.

In the ''Piezodorus lituratus var. alliaceus'' the corium shows a uniform yellow-greenish color.

This species could be confused with the Green Shieldbug , but ''Piezodorus lituratus'' has a different habitat and red antennae.
