What is spotted lanternfly?
In addition to the impact on our tree canopy, it also has the potential to devastate our economy if not contained. It’s estimated the state could lose $324 million annually from the forestry industry.
Life stages and identification
Egg mass (October-June)
You can find egg masses on trees, stones, cars, patio furniture…really anywhere. The masses are 1 inch long and are covered in a white substance that dries over time, looking like mud (blending into things like trees).
Early stage nymph (May-June)
After they hatch, nymphs are very tiny and grow to about 1/4 inch. They have black bodies with white spots. They’re excellent jumpers.
Late stage nymph (July-September)
As late stage nymphs, SLFs get bright red spots in addition to the white. They grow to be 1/2 inch long.
Adult (July-December with egg laying beginning in September)
Adult SLFs are about 1 inch long. Their wings are red closest to their bodies, with tan wings and black spots outside. They like to jump and glide.
What to do when you find SLF
If you find egg masses, this video shows you how to identify, remove, and destroy them. When you find other stages on your property, you should try and destroy it. You can find information on that from the PA Department of Agriculture here.
