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 11 states including: Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, Ohio, Pennsylvania, Virginia, and West Virginia.

Spotted lanternfly (SLF) does not fly long distances, but it is a hitchhiker. Starting in the fall, SLF seek out outdoor surfaces and lay mud-like egg masses on tree bark, outdoor gear (such as lawnmowers, bikes, and grills), methods of transport, and more.

Spotted lanternfly egg masses are about an inch long and resemble a smear of mud. If found in an area known to have an SLF population, residents should crush them and scrape them off. Travelers passing through SLF quarantine areas should thoroughly check their vehicles, trailers, and even the clothes they are wearing to avoid accidently moving the spotted lanternfly from a quarantine area to somewhere new.

If you find this pest outside of a spotted lanternfly quarantine area, please take a picture of it and note the location to report it to your State Department of Agriculture before killing it.

  • 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.
