  • USDA. APHIS. PPQ. CPHST. Identification Technology Program.

    Native to Asia, the spotted lanternfly has quickly spread since its initial detection in 2014. The insect is not a strong flier, yet its U.S. range is expanding, mostly due to the movement of vehicles, outdoor furniture, or other objects to which females glue their inconspicuous egg masses. Includes ID aids to help identify the spotted lanternfly in all its life stages, from egg mass through adult.

  • United States Department of Agriculture.
    U.S. Secretary of Agriculture Sonny Perdue today announced $17.5 million in emergency funding to stop the spread of the spotted lanternfly in southeastern Pennsylvania. The spotted lanternfly, with its distinctive and colorful wings, was first identified in Pennsylvania in 2014. The affected area expanded from 174 square miles in fiscal year (FY) 2016 to approximately 3,000 square miles by the end of FY 2017.
Native To:
Date of U.S. Introduction:
First detected in 2014, but appeared to have been present in the U.S. for 2-3 years (Dara et al. 2015; Barringer et al. 2015)
Means of Introduction:
Possible pathways include imported woody plants, wood products, and other commodities (EPPO 2016)
Poses a serious economic threat to multiple U.S. industries, including viticulture, fruit trees, ornamentals and timber (Urban et al.)

In the U.S., spotted lanternfly is an invasive species that could be very devastating to some New Jersey crops and hardwood trees. In 2018, SLF populations were found in New Jersey and a state quarantine encompassing 3 counties has been established by the NJ Department of Agriculture. People and businesses travelling in and out of Mercer, Hunterdon, and Warren counties should inspect their vehicles for hitchhiking SLF as well as inspect outdoor items such as firewood, paving stones, lawn equipment, etc. for egg masses (see checklist (PDF | 222 KB)). Quarantine compliance will reduce the spread of SLF to new areas and counties thereby protecting New Jersey resources including forests and agriculture.
