Erie, Pennsylvania — a Lake Erie port city of about 94,000 — confirmed spotted lanternfly in 2023, establishing SLF's presence in the far northwest corner of the state. Erie County's mix of waterfront industrial zones, interstate freight corridors, and the ecologically sensitive Presque Isle State Park peninsula create significant management challenges. Pennsylvania is under a statewide SLF quarantine; residents must comply with movement restrictions and report sightings to the PA Department of Agriculture.
