The spotted lanternfly (Lycorma delicatula) is an invasive pest that significantly threatens Long Island's trees, plants, and overall ecosystem. Originally from Asia, this destructive insect has spread rapidly across the United States, wreaking havoc on agriculture and natural landscapes. Understanding how to identify and manage this pest is crucial for safeguarding our environment.
What is the Spotted Lanternfly?
The spotted lanternfly is an invasive planthopper that primarily targets the Tree of Heaven (Ailanthus altissima), itself an invasive species. However, the lanternfly is not picky and will feed on a wide variety of trees and plants, including:
Maple
Birch
Willow
Sycamore
Grape vines
Fruit trees (such as apple and peach)
Oaks
Life Stages and Identification
Identifying the spotted lanternfly at various stages of its life cycle is essential for effective management.
Egg Masses: The first stage of the spotted lanternfly's life cycle. Egg masses look like grayish mud or putty and are often found on tree trunks, branches, rocks, and outdoor furniture. Each mass contains 30-50 eggs.
Nymphs (Early Stage): After hatching, the nymphs are small (about 1/8 inch) and black with white spots. They go through several instars (growth stages), increasing in size but maintaining their black and white coloration.
Nymphs (Late Stage): In the later nymph stages, they develop red patches while retaining their white spots and black coloration. They are about 1/2 inch long at this stage.
Adults: Adult spotted lanternflies are about 1 inch long and have distinctive gray wings with black spots. When their wings are open, you can see a striking red and black pattern on their hindwings, which is a key identifying feature.
Impact on Trees and Plants
The spotted lanternfly feeds by piercing the bark of trees and plants and sucking out sap. This feeding behavior weakens plants, making them more susceptible to disease and other pests. Heavy infestations can lead to:
Reduced fruit yield in orchards and vineyards
Wilting and dieback of branches
Honeydew secretion, which leads to sooty mold growth, further damaging plants
If you spot spotted lanternflies or their egg masses, it's important to take immediate action:
Report Sightings: Report any sightings to local agricultural or environmental authorities. In New York, you can report to the NYS Department of Environmental Conservation.
Destroy Egg Masses: Scrape egg masses into a container with rubbing alcohol or hand sanitizer to kill them. This can significantly reduce the population if done early in the season.
Kill Nymphs and Adults: Use a strong spray of water or insecticidal soap to kill nymphs and adults. Sticky bands around tree trunks can also trap nymphs climbing up the trees.
Remove Tree of Heaven: Since this tree is a preferred host for the spotted lanternfly, removing it from your property can help control their spread.
