Spotted Lanternfly

The spotted lanternfly is a threat to many fruit crops and trees. Learn how to spot it and report it.

The Spotted Lanternfly (Lycorma delicatula) is native to China and was first detected in Pennsylvania in September 2014. Spotted lanternfly feeds on a wide range of fruit, ornamental and woody trees, with tree-of-heaven being one of the preferred hosts. Spotted lanternflies are invasive and can be spread long distances by people who move infested material or items containing egg masses. If allowed to spread in the United States, this pest could seriously impact the country’s grape, orchard, and logging industries.



Spotted lanternfly populations are currently found in 10 states including: Connecticut, Delaware, Indiana, Maryland, New Jersey, New York, Ohio, Pennsylvania, Virginia, and West Virginia.

Spotted lanternfly is a hitchhiker. Be sure to inspect for the pest. Egg masses, juveniles, and adults can be on trees and plants and are also found on bricks, stone, metal, and other smooth surfaces. Also thoroughly check your vehicles, trailers, and even the clothes you’re wearing because you can accidently move spotted lanternfly.
  • Plants that ooze or weep and have a fermented odor
  • Buildup of sticky fluid (honeydew) on plants and on the ground underneath infested plants
  • Sooty mold on infested plants
  • When preparing for the winter holidays, check outdoor items for spotted lanternfly egg masses, including those items you may bring indoors. Scrape any egg masses into a plastic zippered bag filled with hand sanitizer, then zip the bag shut and dispose of it properly.

  • Inspect your trees and plants for signs of this pest, particularly at dusk and at night when the insects tend to gather in large groups on the trunks or stems of plants.

  • Inspect trees (in particular, tree of heaven), bricks, stone, and other smooth surfaces for egg masses.

  • Visit “Where’s the Threat and How to Report” for instruction on how to report a sighting if you find spotted lanternflies outside of quarantine areas.
