What Damage do Spotted Lanternflies Cause?
Lanternflies can be very destructive to trees and plants. They damage trees by feeding on the sap from stems, leaves and tree trunks. They are also known to feed on commercial crops. After feeding on the plants, the insect excretes the carbohydrates from the sap into a honeydew like substance. This sticky honeydew substance helps promote the growth of mold on the plants.
