Spotted lanternfly (SLF), Lycorma delicatula, is an invasive planthopper, native to China, that was first detected in 2014 in southeastern Pennsylvania. It feeds voraciously on many plants, including economically important crops like fruit trees, grapevines, hops, hardwoods, and ornamentals. If you think you have SLF, do not panic! First, make sure the insect you are seeing is the spotted lanternfly. Next determine if you should report your sighting. Third, learn about its life cycle and habits. Fourth, determine what plants it is infesting and what it is not. Fifth, employ management strategies at the proper time of the year.

Spotted lanternflies are still concentrated in Southeastern Pennsylvania, encompassing a 13 county quarantine area. Agronomic crops are not their preferred host but if you see high numbers in field crops, please let us know.

Obtain a Permit (for Businesses)

To stop the spread of spotted lanternfly, the Pennsylvania Department of Agriculture issued a quarantine for counties where the presence of this pest has been confirmed. Businesses operating in the quarantine zone must have permits to move equipment and goods within and out of the zone. Penn State Extension and the Pennsylvania Department of Agriculture have developed this self-paced, online course to train designated employees how to comply with the quarantine.
