****Spotted Lanternfly: What to Look For – Photo Gallery (link is external)****. Become familiar with the different life stages of this pest.
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 observe any egg masses or insects which look similar to this, please try to collect them, and inform the Maryland Department of Agriculture at (410) 841-5920 or Aaron.Shurtleff@maryland.gov (link sends e-mail) as soon as possible.
