Spotted Lanternfly inReading, PASPOTTED LANTERNFLY GUIDE
Reading is Berks County seat — confirmed SLF just one year after the initial Boyertown detection in 2014, making it one of the earliest and most heavily infested cities in the United States. Berks County is widely considered ground zero for the US SLF invasion. The Schuylkill River trail corridor has dense Tree of Heaven populations, and urban neighborhoods throughout Reading are surrounded by SLF-heavy suburbs. Railroad rights-of-way through the city are heavily colonized.

Tree of Heaven in Reading, PA
Reading's Schuylkill River corridor, railroad rights-of-way, and disturbed urban lots have massive Tree of Heaven populations that have supported SLF establishment since the very first years of the US invasion. Neversink Mountain and the Hamburg Reservoir trail extend high-density SLF habitat into the surrounding landscape. Reading remains one of the most heavily infested cities in the nation — a benchmark site for SLF research and management.
