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 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:
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

egg masses) can be submitted to Badbug@pa.gov.
