Psyllid eggs are frequently deposited along leaf margins but may occur on either leaf surface. Eggs hatch in 6 to 10 days. Newly hatched nymphs are yellowish in color, but become progressively greener as they develop, undergoing four molts. When almost mature, nymphs are nearly the same color as leaves. Nymphs are flat, elliptical and scale-like.
Nymphs are most numerous on the undersides of leaves but can occur on shaded upper leaf surfaces.
They are quite inactive and seldom can be seen to move about. While feeding, psyllid nymphs excrete small, waxy beads of material resembling granulated sugar. This material may cover leaves during heavy psyllid infestations. The nymph stage usually lasts from 14 to 22 days. Newly emerged adults remain green for a day or so on the plant before turning darker.
