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.
If you live outside of the current quarantine area in Pennsylvania and find a spotted lanternfly, report it!
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
spotted lanternfly feeds on many types of plants but strongly prefers Tree of
Heaven. Attacked trees 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 sightings of egg masses, nymphs, or adult spotted lanternfly using this tool provided by our partners Penn State Extension.
