The Spotted

How to Combat

Lanternfly

The front wings are grayish and have dark spots, and the back wings are black-tipped, white in the center, and bright red near the body.

How did the Spotted Lanternfly get here?

The native range includes China, India, and Vietnam. It was first reported outside these countries in South Korea in 1932. The insect arrived in Berks County, Pennsylvania, via an overseas shipment in 2014 and has since spread through other states.

In addition to Pennsylvania, the SLF is considered a threat in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, Ohio, Virginia, and West Virginia.

They feed on sap in the phloem of smooth bark, the living tissue in vascular plants, which causes the trees stress and eventual decline.

Early detection is the best defense. If egg masses are found, they can be scraped with a card into a container and destroyed. Catching nymph or adult SLFs is challenging because they are mobile. Sticky traps can hold them until you can dispose of them.
