Spotted Lanternfly

Spotted Lanternfly

The spotted lanternfly is a threat to many fruit crops and trees. Learn to spot it and report it.

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. If allowed to spread in the United States, this pest could seriously impact the country’s grape, orchard, and logging industries.
