SPOTTED LANTERNFLY: The Spotted Lanternfly, Lycorma delicatula, an invasive planthopper, has been discovered in Berks County, Pennsylvania. It is native to China, India, Vietnam, and introduced to Korea where it has become a major pest. This insect has the potential to greatly impact the grape, hops and logging industries. Early detection is vital for the protection of Pennsylvania businesses and agriculture.
If you live outside of the current (quarantine area) in P. A. and find a spotted lanternfly, report it! Use this interactive Plant Pest Quarantine Search to see if you’re in the spotted lanternfly quarantine area.
The Spotted Lanternfly adult is approximately 1” long and 1/2” wide at rest. The forewing is grey with black spots and the wings tips are reticulated black blocks outlined in grey. The hind wings have contrasting patches of red and black with a white band. The legs and head are black; the abdomen is yellow with broad black bands. Immature stages are black with white spots, and develop red patches as they grow.
Signs & Symptoms:
Trees, such as tree of heaven and willow, will develop weeping wounds. These wounds will leave a greyish or black trail along the trunk. This sap will attract other insects to feed, notably wasps and ants. In late fall, adults will lay egg masses on host trees and nearby smooth surfaces like stone, outdoor furniture, vehicles, and structures. Newly laid egg masses have a grey mud-like covering which can take on a dry cracked appearance over time. Old egg masses appear as rows of 30-50 brownish seed-like deposits in 4-7 columns on the trunk, roughly an inch long.
What to do:
If you see egg masses, scrape them off, double bag them and throw them away. You can also place the eggs into alcohol or hand sanitizer to kill them. Please report all destroyed egg masses on our website.
Collect a specimen: Specimens of any life stage can be turned in to the Pennsylvania Department of Agriculture’s Entomology lab for verification. Submit samples with the Entomology Program Sample Submission Form.
Take a picture: A photograph of any life stage (including egg masses) can be submitted to Badbug@pa.gov.
Report a site: If you can’t take a specimen or photograph, call the Automated Invasive Species Report Line at 1-866-253-7189 and leave a message detailing your sighting and contact information.
Currently a quarantine is in place to stop the movement of this pest to new areas and to slow its spread within the quarantine. The quarantine affects a variety of plant, wood and stone products. Surveys are currently underway to determine the complete spread of this pest in Southeastern Pennsylvania. Efforts are also underway to ensure the Spotted Lanternfly is not present in other parts of the commonwealth.
