Lace bug species are common, but each species feeds on only one or a few closely related plants, including alder, ash, Baccharis, birch, ceanothus, fruit trees, photinia, poplar, sycamore, toyon, walnut, and willow. Nymphs are smaller, oval, and spiny. All stages occur in groups on the undersides of leaves. After five molts over a period of about 6 weeks, the adult stage appears. Most species overwinter as adults under bark plates, under fallen leaves, or as eggs in leaves on evergreen hosts.
Lace bugs have several generations a year.
Provide proper cultural care so plants are vigorous. No treatment will restore stippled foliage, which remains until pruned off or replaced by new growth. In the eastern United States where the azalea lace bug, Stephanistis pyricides, is a pest, research suggests that natural enemies may be effective against this lace bug in shady habitats with diverse vegetation and abundant leaf litter or natural mulch. Cultural Control Grow plants well adapted to conditions at that site. Plants in hot, sunny locations are more likely to be damaged.
