Spotted lanternfly is a large, sap-feeding planthopper that feeds from the phloem tissue of host plants. These insects have four wings and a piercing-sucking mouthpart that is used to pierce their food source and suck out nutritive fluids. Spotted lanternfly is not a fly, but a type of planthopper (order Hemiptera, family Fulgoridae). Spotted lanternfly nymphs and adults have been reported feeding on wild and domestic grapes, hops, fruit trees, willow, various hardwood trees, pines, shrubs, and vines. SLF, however, feeds on a wide variety of plants throughout its life cycle, with nymphs reported as having a more diverse palate than their adult counterparts. The preferred host of SLF is Tree of Heaven (Ailanthus altissima) another introduced invasive species. Residents can also report suspected finds via the Great Lakes Early Detection Network (GLEDN) mobile app. Residents are asked to be vigilant and report any suspected finds by calling a local Ohio State University Extension office or by using the Ohio Department of Agriculture website.
