	Eggs: Eggs are yellowish-brown to a very dark bronze-brown depending on age. They are elliptical and about 1/16 inch (1.6 mm) long. Eggs are laid in clusters on the undersides of leaves in the angle formed by the veins. The clusters usually contain a few dozen eggs lying on their sides arranged in rows in two directions meeting each other at an acute angle. The eggs hatch in about one to two weeks.
	Nymphs: The nymphs have a green abdomen with crimson head, thorax, antennae and legs but soon darken to reddish brown. Older nymphs are grayish white with black legs and antennae. The nymphs range in size from 3/16 to 1/2 inch (5 -13 mm) in length.
