Spotted Lanternfly Found in New York State

09/20/2018 - The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) confirmed on Sept. 11, that spotted lanternfly (SFL) was found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private Keuka Lake property in Penn Yan, Yates County.

Following both reported cases, DEC and DAM immediately began extensive surveys throughout the area. At this time, no additional insects have been found. Extensive trapping surveys will continue in high-risk areas throughout the state as well as inspections of nursery stock, stone shipments, commercial transports, etc. from Pennsylvania.

In addition, surveying for this insect is part of the Cooperative Agricultural Pest Survey (CAPS) program, which is carried by out Cornell Cooperative Extension Educators in partnership with New York State Department of Agriculture and Markets in regions across New York State. DEC and partner organizations encourage everyone to be on the lookout for this pest. New Yorkers are urged to report potential sightings to spottedlanternfly@dec.ny.gov.

Spotted lanternfly (SLF) is an invasive pest native to China and Southeastern Asia. It was first discovered in Pennsylvania in 2014 and has since been found in New Jersey, Delaware and Virginia. SLF feeds on more than 70 plant species including grapes, hops, apples and stone fruits.

It is a destructive pest that can pierce the plant and suck up sap. Both nymphs and adults feed this way, on leaves, stems, and trunks. Feeding by SLF stresses plants, making them vulnerable to disease and attack from other insects. SLF also excretes a large amount of "honeydew" which may attract other insects.

Nymphs are black with white spots and turn red before transitioning into adults. They can be seen as early as April. Adults begin to appear in July and are approximately 1-inch-long and inch wide at rest, with eye-catching wings. Their forewings are grayish with black spots. The lower portions of their hindwings are red with black spots, and the upper portions are dark with a white stripe. In the fall, adults lay 1-inch-long egg masses on nearly anything from tree trunks and rocks to vehicles and firewood. They are smooth and brownish-gray with a shiny, waxy coating when first laid.
