The invasive spotted lanternfly, a planthopper native to Asia, continues to expand its presence across the Northeastern United States. In August 2026, populations were observed throughout New Jersey, with sightings occurring in areas such as Abury Park and along coastal boardwalks. These insects pose a threat to local ecosystems and agriculture by feeding on various plants and trees.

By late August 2026, the species was officially detected for the first time in New Hampshire. A small number of insects were identified in Salem, though the New Hampshire Department of Agriculture, Markets, and Food stated there was no evidence of an established population at that time. Multi-agency surveys have been initiated to determine the extent of the presence in the state.
