Spotted Lanternfly inNew Rochelle, NYSPOTTED LANTERNFLY GUIDE
New Rochelle — a dense suburban-urban city of 79,000 in southern Westchester County — confirmed SLF in 2021. Positioned as the northeastern gateway on I-95, New Rochelle is a primary conduit for SLF moving from the heavily infested New York City metro into Connecticut and southern New England. Metro-North's New Haven Line runs directly through the city, concentrating commuter traffic that accelerates SLF dispersal. Echo Bay's waterfront parks and the Long Island Sound shoreline provide Tree of Heaven habitat along the coast. Iona University's campus adds monitored green space, and the dense suburban-urban transition zone throughout the city sustains established SLF colonies.

Tree of Heaven in New Rochelle, NY
The I-95 / New England Thruway corridor through New Rochelle is a critical SLF transport artery — one of the highest-traffic freight and passenger vehicle routes on the East Coast, with Tree of Heaven established along highway margins throughout the city. Metro-North New Haven Line rail margins are documented SLF spread corridors connecting New Rochelle to the confirmed infestation zones of White Plains and Yonkers to the north and Westchester's southern communities. Echo Bay waterfront and the Long Island Sound shoreline have established TOH populations providing prime SLF habitat along New Rochelle's coastal edge. The dense suburban-urban transition zone throughout the city creates a complex SLF monitoring landscape requiring active community engagement.
