Lace bugs are sucking insects that feed on plant fluids. Feeding injury causes yellow spotting on leaves, which may turn brown and fall off the plants.

Lace bug developmental stages are egg, nymph (five instars) and adult. Development time varies with species and geographic location. There are multiple generations per year. Nymphs have spine–like projections on their bodies. Adults have wings with very elaborate designs on them. Depending on the species Lace bugs overwinter as eggs or adults, and become active in the spring.
