The Spotted Lanternfly (Lycorma delicatula) is native to China and was first detected in Pennsylvania in September 2014. Spotted lanternfly feeds on a wide range of fruit, ornamental and woody trees, with tree-of-heaven being one of the preferred hosts. Spotted lanternflies are invasive and can be spread long distances by people who move infested material or items containing egg masses. Juvenile spotted lanternflies, known as nymphs, and adults prefer to feed on the invasive tree of heaven (Ailanthus altissima) but also feed on a wide range of crops and plants including grapes, apples, hops, walnuts and hardwood trees.
