Nymphs lack the lace-like wings, but by the time these insects are noticeable on plants, both nymphs and adults are usually present. Most lace bugs live on the lower surface of the leaf. Nymphs are flattened and spiny in appearance. Infested plant materials show dark fecal spots and cast nymphal skins along with the nymph and adult population. Adults are not likely to fly when disturbed.
Lace bugs have piercing-sucking mouthparts.
They use these to pierce host leaves, after which leaves take on a stippled appearance. Eventually the leaf may turn yellow and drop prematurely. Heavy infestations early in the season stress host plant material, which can lead to death of the plant. Three to five generations are produced each year. Azalea and rhododendron lace bugs overwinter in the egg stage.
