What is spotted lanternfly?
The spotted lanternfly threatens many fruit crops and trees. Learn how to spot it and report it.
First discovered in Pennsylvania in 2014, it has become a major pest in that state and spread to several surrounding states. Interceptions of dead SLF specimens have taken place in Oregon and California during regulatory inspections. WSDA has responded to a number of reports in Washington that have all turned out to be negative.
Spotted lanternfly feeds on a wide range of fruit, ornamental and woody trees, with tree-of-heaven being one of the preferred hosts.
