Many kinds of lace bugs, family Tingidae, feed on landscape plants throughout the United States. 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.
