Piercing mouthparts allow Lace Bugs to drain needed fluids from leaves, damaging the appearance of plants but little else.

Dainty and delicate wings of Lace Bugs resemble fine lace. They are small insects and can be found on plants in all life stages. Eggs are laid by females under leaves. Nymphs hatch and join adults in drinking from the leaf they are on. Small black dots of feces on the leaf become visible and the leaf begins to dry out and die. Robbing a plant of it photosynthetic parts can impact the plants overall health though Lace Bugs are not known to cause plant death, just leaf drop. Without leaves, some varieties of developing fruit like avocados can receive more sunlight which can scorch them a bit.

Despite their impact on leaves, Lace Bugs do not merit an all-out assault by a gardener. If the aesthetics of the affected plant are important, insecticidal soap or neem oil can help prevent further damage though nothing can repair damage already done. If the appearance of the plant isn't important, waiting out the Lace Bugs is recommended. Wasps and other natural predators will eventually help control their numbers at no charge.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
