The Spotted Lanternfly (SLF) is an invasive planthopper, first discovered in New York City in July 2020. While it can infest trees, it is not considered a widespread threat to our city’s forests. However, it is a significant threat to a wide range of agricultural crops including walnut, grapes, hops, apples, blueberries, and stone fruits.
SLF adults are very colorful when their wings are displayed during hopping. They have red hind wings with black spots, have a black head, and a yellow abdomen with black bands. Their grayish forewings have black spots with a distinctive black brick-like pattern on the tips.
While these insects can jump and fly short distances, they spread mainly through human activity. SLF can lay their eggs on any number of surfaces, such as vehicles, stone, rusty metal, outdoor furniture, and firewood. Adult SLF can hitch rides in vehicles, on any outdoor item, or cling to clothing or hats, and be easily transported into and throughout New York.

Help Prevent the Spread of SLF
Harming city’s wildlife is prohibited. However, in an effort to slow the spread of this species, if you see a Spotted Lanternfly you should squish and dispose of it.
You should thoroughly inspect vehicles, luggage and gear, and all outdoor items for egg masses and adult SLF before leaving the New York City region.
