The Spotted Lanternfly, Lycorma delicatula (White), 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 impact the grape, hops and logging industries greatly. Early detection is vital for the protection of Pennsylvania businesses and agriculture.
If you live outside of the current (quarantine area) in Pennsylvania and find a spotted lanternfly, report it! Use this interactive Plant Pest Quarantine SearchOpens In A New Window 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 the 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.
