The Spotted Lanternfly, an Invasive Pest on the Move in Pennsylvania and Delaware. Moving Closer to Maryland!

Update: 12/2017 

A press release issued from the Delaware Department of Agriculture dated November 20, 2017 confirmed the finding of spotted lanternfly in New Castle County. Delaware is now the second state to report this destructive insect. In Pennsylvania, it has now spread into 13 counties.

The spotted lanternfly is an invasive insect that attacks grapes, apples, stone fruits, pines, and other species. This non-native invasive pest was first detected in the United States in 2014 in Berks County, Pennsylvania but is spreading to other counties in the state. Maryland residents should be on the lookout.

Adults lay eggs on multiple flat surfaces including the outsides and undersides of vehicles which allows them to spread. Egg masses will hatch in the spring. Both nymphs and adults of spotted lanternfly cause damage when they feed, sucking sap from stems and leaves. This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant’s death.

If you should see this insect in Maryland, contact the Home and Garden Information Center. Go to 'Ask Maryland's Garden Experts' to report your sighting. Attach a digital photo of the pest with your question.
