Treehoppers, cicadas, and tree crickets insert eggs inside woody stems, twigs, or canes, causing unsightly scars and split or broken twigs. Cicada nymphs drop to the ground and burrow to tree roots, where they feed on sap--some for as long as 17 years. Treehopper nymphs drop from twigs to feed on legumes and grasses.
Control with recommended insecticide or dormant oil sprays. Tree crickets may damage berry fruits but are easily killed with insecticide sprays early in the season.
