Molting usually occurs at night or in the early morning. The first two nymphal instars are covered with a white powder or dust. Compared to the first and second nymphal stages, the third instars are much wider in proportion. The rest of the body is pale green and has less of a white powdery coating than the younger stages. The fourth nymphal instars are yellowish-green marked with red, black and pink marking.
Legs are pink.
About half way through this stage, a striking change occurs in the appearance of the instars. The new red markings found in the earlier portion of this stage fade to yellow-green, paler than the rest of the insect body such that the insect changes from mostly red to green. It takes about 2 weeks for this color change to occur. Instars are devoid of the white powdery covering. Like the fourth instars, the fifth instars also go through a color change.
