The NYC Parks Department is tracking the impact of the Spotted Lanternfly (SLF) infestation, and is coordinating with state and federal agencies in surveying and treatment approaches.
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.
Harming city’s wildlife is prohibited, but in an effort to slow the spread of this species, NYC Parks is putting out a one-time call: if you see a Spotted Lanternfly, squish and dispose of it.
You can help prevent the spread of SLF by refraining from moving firewood, outdoor furniture, and other outdoor items that may contain SLF egg masses.
