The Spotted Lanternfly (Lycorma delicatula) is an invasive pest that has been making headlines as it spreads across the eastern U.S. Originally from Asia, it poses a significant threat to trees and plants commonly found in both residential and commercial landscapes. While it has not yet been found in widespread populations in North Carolina, a few sightings have occurred, and early detection is key to protecting our outdoor environments.
What to Look For
Adult Spotted Lanternflies are about an inch long, with gray wings speckled in black and bright red underwings visible when they fly. Immature stages (nymphs) begin as black with white spots, later turning red with black and white patches.
These pests are often found on the trunks and branches of trees or large shrubs—especially Tree-of-Heaven (Ailanthus altissima), a known host plant—but they also feed on maples, birches, walnuts, willows, and many ornamental trees commonly used in landscapes.
Why It Matters for Landscapes
Spotted Lanternflies feed by piercing the bark and stems of plants and sucking out sap. This weakens the plant, leaving it vulnerable to disease and environmental stress. In addition, the insects excrete a sticky substance called honeydew, which can coat leaves, hardscapes, and outdoor furniture. This residue promotes the growth of black sooty mold and creates a mess that’s hard to ignore.
Over time, repeated infestations can:
Reduce the health and appearance of landscape trees and shrubs
Lead to dieback or plant decline
Create maintenance challenges due to honeydew and mold
Attract additional insect pests
What to Do If You See One
If you suspect Spotted Lanternflies are present in your landscape:
Take a clear photo for documentation.
Collect a sample if possible (seal it in a bag or container).
Report it immediately to the NC Department of Agriculture & Consumer Services or your local Cooperative Extension office.

Do not attempt to move infested plants or materials off-site, as this can contribute to the pest’s spread.
