First Confirmed Arrival in the United States
Lanternflies, specifically the spotted lanternfly (Lycorma delicatula), were first found in the United States in Berks County, Pennsylvania, in 2014. The initial discovery was linked to a shipment of stone from Asia.
How Quickly Did Lanternflies Spread After Arrival?
Within a few years, lanternflies expanded from Berks County into much of eastern Pennsylvania and neighboring states. By 2021, they had been confirmed in multiple states, including New Jersey, Delaware, Maryland, Virginia, and West Virginia, often moving along transportation corridors and freight routes.
Why Early Detection Matters for Agriculture and Homeowners
Lanternflies feed on sap from trees, vines, and crops, weakening plants and promoting mold growth. Their honeydew secretions attract other pests and can damage fruit harvests and outdoor surfaces. Early detection helps homeowners and growers respond before populations grow large.
