Spotted lanternfly (SLF) threatens fruit crops like grapes, peaches, and hops. It also threatens numerous tree species, such as pine, oak, walnut, and maple.  However, its preferred host is another invasive species: tree-of-heaven (Ailanthus altissima). SLF is an insect native to East Asia. In 2016, it was discovered in southeast Pennsylvania. It was confirmed in Virginia in January 2018. If you think you have found SLF, collect a specimen or take photos and notify Virginia Cooperative Extension.
