What is a spotted lanternfly?
It was first detected in the United States in 2014 in southeastern Pennsylvania and has been spreading since. Infestations have been confirmed in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Virginia, and West Virginia.
What do they look like?
Adult spotted lanternflies are roughly 1 inch in length. Their front wings are gray with black spots and feature speckled bands at the tips. The rear wings are red with black spots and a white band. They have black heads and legs, while their abdomens are yellow with black stripes.
Despite their striking red bodies and unique spotted wings, the spotted lanternfly is far more harmful than attractive. It must be eradicated before it turns into an uncontrollable swarm that damages agriculture and local businesses.
Why is this bug a problem?
The spotted lanternfly feeds on over 70 plant species, including grapes, apples, hops, and hardwood trees.
Although these insects are not harmful to humans or animals, they pose a significant threat to the environment and local economies. Penn State economists estimate that spotted lanternflies could cause up to $324 million in annual damage in Pennsylvania alone.
While they are not capable of flying long distances, they can lay eggs on almost any surface.
Eggs have been found on cars, trailers, firewood, outdoor furniture, and other items.
Individuals and businesses receiving shipments from states where the spotted lanternfly is present should carefully check goods and packaging for egg masses.
How does the spotted lanternfly cause damage?
The spotted lanternfly extracts sap from host plants and releases large quantities of a sugary, sticky substance known as honeydew.
This honeydew, along with the black sooty mold it causes, can damage plants and stain surfaces. Additionally, the honeydew draws pests such as yellow jackets, flies, and ants.
