Spotted Lanternfly inBuffalo, NYSPOTTED LANTERNFLY GUIDE
Erie County confirmed SLF in 2023, making Buffalo — the westernmost major city in New York State with SLF detection — a critical node in SLF's continued westward push toward the Great Lakes region. The I-90/I-190 Niagara Frontier hub is one of the busiest freight corridors in upstate New York, and the Peace Bridge to Canada creates an international SLF dispersal risk. Lake Erie waterfront, the Canalside historic district, and Delaware Park — Frederick Law Olmsted's landmark design with diverse tree plantings — are all under active monitoring. University at Buffalo's large suburban campus adds significant green space at the leading edge of the western New York spread front.

Tree of Heaven in Buffalo, NY
Buffalo's Lake Erie waterfront and Canalside historic district have Tree of Heaven established along the water's edge — providing prime SLF habitat at the westernmost confirmed detection point in New York State. The I-90/I-190 Niagara Frontier interchange is a critical SLF dispersal hub, with heavy freight traffic from Pennsylvania, Ohio, and Ontario moving egg masses through the region. The Peace Bridge Canada border crossing freight zone represents a significant international spread risk. Delaware Park's Olmsted-designed landscape with diverse tree plantings is a priority monitoring site, and the University at Buffalo North Campus adds substantial suburban green space on the western New York SLF watch front.
