Spotted Lanternfly inSpringfield, MASPOTTED LANTERNFLY GUIDE
Hampden County confirmed SLF in 2023, placing Springfield — the Pioneer Valley gateway city — at the leading edge of SLF establishment in western Massachusetts. The Connecticut River valley corridor is a natural SLF spread highway connecting populations from Hartford, CT, northward through Springfield and into the Pioneer Valley. The Mass Pike (I-90) is a primary vehicle-based spread vector, and rail connections to Hartford and Boston make Springfield a key dispersal node. Forest Park, one of the largest urban green spaces in New England, provides extensive Tree of Heaven habitat throughout the city.
