Spotted lanternfly, bane of fruits and hardwood alike: A fall update

Spotted lanternfly continues to spread leaving dying and sickly grapes, fruit trees, and hardwoods in its wake. We told you about them earlier this year, but are back with some updates.

Spotted lanternfly is an invasive planthopper that is currently found in Pennsylvania, New Jersey, and Virginia and has been spotted in Delaware and New York. This insect’s flashy pink, black, and orange coloration make them easy to spot in the nymph and adult stages but the eggs blend seamlessly into stone, bark, and lumber. These invasive insects weaken plants and make them more prone to infection by piercing bark to feed and dripping sugary excrement onto the ground.

Right now, there is a great risk of spread. Anecdotal reports suggest that adults may be adept at clinging to moving vehicles which may be aiding in their dispersal. You should be on the lookout for eggs and adults attached to merchandise and vehicles coming from the affected states. If you suspect you might have found any, report it (learn how at!

Researchers at Penn State have been working hard to improve containment and management. To learn more check out:
