The spotted lanternfly (Lycorma delicatula) is an invasive planthopper currently spreading through the Mid-Atlantic and Northeastern United States. Spotted lanternfly was first found in Rhode Island in August of 2021 (see press release). A year later in August of 2022, the RIDEM and USDA confirmed the first population of SLF in Rhode Island (see press release). SLF feeds on many different plants, including grapevines, maples, black walnut and other important species.
