Spotted Lanternfly inState College, PASPOTTED LANTERNFLY GUIDE
State College — Centre County and Pennsylvania's largest borough — confirmed SLF in 2019. Penn State University's main campus is simultaneously the epicenter of US SLF research and a heavily infested landscape: Penn State's College of Agricultural Sciences and Entomology Department lead national SLF research programs while managing active infestations across the university's 8,000-acre campus and grounds. The I-99 corridor connects State College to the broader Pennsylvania SLF infestation zone, and Beaver Stadium's massive fall football traffic brings hundreds of thousands of vehicles from across the state during peak adult SLF season. The Nittany Creek tributary corridor and College Avenue commercial district provide urban SLF habitat through the borough core.

Tree of Heaven in State College, PA
Penn State University's campus is uniquely positioned as both the leading US SLF research institution and a heavily infested landscape — entomologists study the pest in their own backyard, making this the most monitored SLF site in the country. The Nittany Creek tributary corridor has established Tree of Heaven along its banks, providing natural SLF habitat running through State College's residential and campus landscape. I-99's commercial corridor margins have TOH colonization connecting State College to the broader central PA infestation zone. Beaver Stadium's six home football games each fall bring 107,000+ fans per game from across Pennsylvania — representing a massive recurring vehicle-based SLF egg mass transport event during peak adult season.
