Spotted Lanternfly
Spotted lanternfly (Lycorma delicatula) is an invasive planthopper that feeds on a wide range of plants, including grapes, hops, stone fruits, and hardwood trees. When the spotted lanternfly feeds, it excretes a sticky, sugary fluid that causes sooty mold, which can further damage plants. Its preferred host is tree of heaven (Ailanthus altissima), and today 18 States have some degree of infestation.
It is native to east Asia. Found in Pennsylvania in 2014 and has since spread east and south with infestations as far west as Chicago. It is spread by humans moving the egg masses laid on bricks, shipping containers, propane tanks, and other smooth surfaces.
- While tree of heaven is not found in North Dakota, grapes are becoming an important crop.
- No natural predators of Spotted Lanternfly in North Dakota.
- The pest can devastate grape vines.
- The sooty mold growing on the honeydew can create a mess to clean off of decks, picnic tables, and playground equipment.
