Spotted Lanternfly inBroome County, NYSPOTTED LANTERNFLY GUIDE
Broome County — with Binghamton as county seat, anchoring the Triple Cities metro of Binghamton, Johnson City, and Endicott — confirmed SLF in 2021, placing the Susquehanna River headwaters region squarely within the expanding infestation zone. The county sits at the confluence of the Susquehanna and Chenango rivers, within the same watershed that drains southward through heavily infested Pennsylvania SLF territory. The I-88/I-81 highway intersection is one of upstate New York's most significant transport nodes, connecting the Southern Tier to the Capital District, the Catskills, and central Pennsylvania — all established or expanding SLF zones. SUNY Binghamton's wooded campus and adjacent nature preserve provide significant ecological monitoring capacity for tracking SLF spread across the Susquehanna corridor.

Tree of Heaven in Broome County, NY
Tree of Heaven is established along the Susquehanna and Chenango river corridors through Broome County, providing continuous SLF host habitat from the Pennsylvania border northward into the heart of the Triple Cities metro. The I-88 and I-81 road margins have Ailanthus colonization that extends SLF dispersal pathways through the county's major freight corridors. SUNY Binghamton campus edges and the river waterfront greenways are priority monitoring zones as SLF populations continue to establish in this Southern Tier river city.
