Spotted lanternfly (SLF) is an invasive sap-feeding insect from Asia that was first found in the United States in 2014, in Pennsylvania. While the main host plant of this pest is tree-of-heaven (Ailanthus altissima), SLF attacks a variety of trees, shrubs, and vines, and has the potential to impact a broad range of agricultural commodities, including grapes and wine, apples, peaches, and maple syrup. The first known infestation of spotted lanternfly in Massachusetts was found in 2021.
