Pest Alert: Spotted Lanternfly is an Invasive Insect That May Impact Oregon

Spotted Lanternfly has a broad range of plant hosts, including grape, stone fruits, apple, ornamental species, maple, black walnut, willow and rose. Nymphs and adults are phloem feeders. They suck sap from young stems and leaves, which can cause wilting and plant stress. High numbers of Spotted Lanternfly can reduce photosynthesis, weaken the plant and eventually contribute to the host plant’s death.
