What is the Spotted Lanternfly?

The Spotted Lanternfly is an invasive planthopper native to southeast Asia and first identified in Bucks County Pennsylvania in 2014 that has since traveled to Berks, Carbon, Chester, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia, and Schuylkill Counties. The invasive insect feeds on agricultural goods such as apples, grapes, hardwood, and hops. The Spotted Lanternfly adult is approximately one-inch long and a half-inch wide at rest. The forewing is grey with black spots, and the wings tops are reticulated black blacks outlined.

How much damage can Spotted Lanternfly cause?

Spotted Lanternfly has the potential to cause a lot of damage to Pennsylvania's Agricultural commodities. They suck sap from stems and leaves. This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant's death. Spotted Lanternfly can damage grapes by feeding on the vines and producing honeydew when the honeydew molds it can cause dieback or damage to the fruit.

It is now the time of year where Spotted Lanternfly adults began to lay egg masses. So please, look before you leave! Spotted Lanternfly adults frequently gather in large numbers and they are easiest to spot at dusk or at night.
