SPOTTED LANTERNFLY: An Invasive Planthopper

SPOTTED LANTERNFLY: An Invasive Planthopper
Guideline to management and eradication

The Spotted Lanternfly, Lycorma delicatula (White), an invasive planthopper, has been discovered in Berks and surrounding counties in Pennsylvania. It is native to China, Bangladesh, Vietnam, and introduced to Japan and Korea where it has become a major pest of grapes. 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.

Property owners can help contain and control spotted lanternfly (SLF) by implementing a management strategy using a combination of mechanical control, host reduction, and chemical control. These guidelines have been developed for use by the Pennsylvania Department of Agriculture (PDA) Spotted Lanternfly Eradication Program. The guidelines target SLF at different stages of its lifecycle, and may lead to dramatic reduction in SLF populations where implemented.


Newly laid spotted lanternfly egg masses (which appear in the fall) have a gray, mudlike covering, which can become dry and cracked over time. Older egg masses may lose their covering and appear as four to seven columns of seedlike eggs, 30-50 eggs in total, approximately one inch long.

Nymphs begin to appear in late April through early May and develop through four stages called instars, all of which are wingless and incapable of flight. The first three nymphal stages are black with white spots. Fourth instars appear in early July and develop red patches on the body and are over a half inch long.

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.


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 sightings of egg masses, nymphs, or adult spotted lanternfly using this tool provided by our partners Penn State ExtensionOpens In A New Window.
