- Egg masses: found on trees (September through May)
- Early nymphs: black with white spots (April through October)
- Late nymphs: black and red with white spots (April through October)
- Adults: black bugs with white/red wings and black spots (July through November)
What are they and why are they bad?
- Invasive planthoppers native to eastern Asia
- First spotted in Pennsylvania in Berks County (2014)
- Attracted to tree-of-heaven, but can greatly impact agricultural crops
- Can reduce the quality of life for people living in heavily infested areas
What do I do if I see one?
- Quarantine them. Inspect your vehicles and other items before transporting them; remove any insects before changing locations so their presence does not spread.
