Pest description and damage Leafhoppers are slender, delicate sucking insects about 0.125 inch or less in length. They are distinguished by the ability of adults and nymphs to run forwards, backwards and sideways to escape danger. Leafhopper feeding on leaves results in damage that resembles small white to yellow stipples in leaves, leaf curling or virus symptoms, as some leafhoppers transmit virus diseases. Sometimes, the tips of hollyhock leaves may die and turn brown. Some leafhoppers exude copious honeydew. Normally, leaf stippling is not injurious to the plants unless the leafhopper carries a virus.
