I saw spotted lanternflies in Clinton County for the first time several days ago. I still have not seen any in Centre County.I’ve seen a huge decrease in lantern flies over the last couple years. I’m in SE PA, I’d say right around Covid time there was thousands, this summer I’ve maybe seen 10. Are they just working their way west towards you guys?
About 2 years ago I saw large numbers of them in Mifflintown, Juniata County.
In both cases I saw them all over ailanthus (tree of heaven).
