Leafhopper feeding causes stippling of plant leaves that is similar to damage caused by two-spotted spider mite. Leafhopper feeding can result in leaf distortion, chlorosis, plant stunting, leaf curling, leaf yellowing and necrosis. Extensive feeding damage gives plants a scorched appearance. Both the adults and nymphs are active, typically moving sideways when disturbed.
Leafhoppers feed on a wide variety of herbaceous perennials. The aster leafhopper transmits aster yellows disease.
Remove weeds from adjacent areas – many weeds serve as a reservoir for leafhoppers. Contact insecticides may be used against leafhoppers, but control can be difficult because leafhoppers are very mobile.
