Why You Should Care

The Spotted Lanternfly is a serious invasive pest with a healthy appetite for our plants and trees — and can be a significant nuisance, affecting the quality of life and enjoyment of the outdoors. If not contained, spotted lanternfly potentially could drain Pennsylvania’s economy of at least $324 million annually, according to a study carried out by economists at Penn State. The spotted lanternfly uses its piercing-sucking mouthpart to feed on sap from over 70 different plant species. It has a strong preference for economically important plants including grapevines, maple trees, black walnut, birch, willow, and other trees. The feeding damage significantly stresses the plants which can lead to decreased health and potentially death.
