Caterpillars are attacked by many beneficial insects. Add a few drops of liquid detergent, which helps the spray stick to the leaves. Bacillus thuringiensis is most effective against small caterpillars, but must make contact with them to be effective. They scar leaves and drink sap from the wounds. May be red, yellow, greenish or spotted.
Adults spin loose webs on foliage and reproduce rapidly in hot weather.
