What is the spotted lanternfly?

Display of pinned adult spotted lantternfly
The spotted lanternfly is an invasive insect that is currently in the mid-Atlantic United States and has the potential to invade California and have a profound impact on our agriculture and our landscapes. 

The spotted lanternfly feeds on sap of many different plants including grapevines, maples, black walnut, and other agricultural and environmentally important plants. An important key to slowing this unwelcome invader is early detection and rapid response, which requires education of citizens and resource professionals.
