The Spotted Lanternfly, also known as the SLF, is an invasive pest from Asia that primarily feeds on tree of heaven (Ailanthus altissima) but can also feed on a wide variety of plants such as grapevine, hops, maple, walnut, fruit trees and others. This insect could impact New York's forests as well as the agricultural and tourism industries.
Where are they located?
SLF were first discovered in Pennsylvania in 2014 and have since been found in New Jersey, Delaware and Virginia. In New York, a dead insect was found in Delaware County in the fall of 2017. As of spring 2018, New York has no infestations, though it's possible they are present in low numbers and have not been detected yet. Given the proximity of the Pennsylvania infestation, it is expected to be found in New York eventually.
What is being done?
DEC is working with the NYS Department of Agriculture and Markets (DAM) and the US Department of Agriculture (USDA) to address SLF. Since it is less expensive and easier to deal with a pest before it becomes widespread, the goal is to find SLF early or prevent it from entering NY altogether.
What can you do?
- Learn how to identify SLF.
- Inspect outdoor items such as firewood, vehicles, and furniture for egg masses.
- If you visit states with SLF, be sure to check all equipment and gear before leaving. Scrape off any egg masses. Visit the Pennsylvania Department of Agriculture webpage (leaves DEC website) for more information on SLF in PA.
If you believe you've found spotted lanternfly in New York...
- Take pictures of the insect, egg masses and/or infestation signs as described above (include something for scale such as a coin or ruler) and email to firstname.lastname@example.org.
- Note the location (address, intersecting roads, landmarks or GPS coordinates.)
- Report the infestation to iMapInvasives.
