Spotted Lanternfly

Spotted Lanternfly Control

The Spotted Lanternfly (Lycorma delicatula) is an invasive planthopper first found in Berks County, PA and now present across multiple counties and states. It threatens grapes, hops, trees, and forest products. Early detection and proper control are critical to protect Pennsylvania businesses and agriculture.

Identification

Adults are ~1″ long at rest. Forewings are gray with black spots and reticulated tips; hind wings show red and black patches with a white band. Nymphs are black with white spots, turning red/black in later stages. Look for weeping sap on hosts (e.g., tree-of-heaven, willow), sooty mold, and egg masses on smooth surfaces.
