Spotted Lanternfly (SLF), Lycorma delicatula, is an invasive planthopper native to China, India, and Vietnam; it is also established in South Korea, Japan and the U.S. It was first discovered in the U.S. in Pennsylvania in Berks County in 2014 and has spread to other counties in PA, as well as the states of New Jersey, Delaware, Maryland, Virginia, West Virginia, New York, Connecticut and Ohio.

This insect has the potential to greatly impact agricultural crops and hardwood trees. SLF feeds on the plant sap of many different plants including grapevines, maples, black walnut, and other important plants in NJ. While it does not harm humans or animals, it can reduce the quality of life for people living in heavily infested areas.
