Spotted Lanternfly inMorristown, NJSPOTTED LANTERNFLY GUIDE
Morristown sits in Morris County — among the first New Jersey counties to confirm SLF establishment in 2020. The Revolutionary War historic sites harbor old tree stands that create prime SLF habitat, and the NJ Transit Morris & Essex commuter line is a major spread vector connecting populations across the county. Heavy tree coverage throughout this commuter township sustains large SLF populations.
