Spotted Lanternfly

An insect that attacks grapes, apples, stone fruits, and pines, and threatens Pennsylvania and the United States.

The spotted lanternfly, Lycorma delicatula, lays egg masses of 30-50 eggs wherever there's a flat surface.  Any smooth-trunked tree, stone, or vertical smooth surface can provide a potential host for eggs masses. Manmade items like vehicles, campers, yard furniture, or any other items stored outside and easily transported, are suitable sites for egg laying and help it spread quickly.

Therefore, a general quarantine over any area found to harbor the spotted lanternfly means that any material or object that can spread the pest cannot be moved. For the most current quarantine information visit the Pennsylvania Department of Agriculture's Spotted Lanternfly site.

Experts are still learning about this threat to agriculture in Pennsylvania and the United States and how to combat it.
