Re: lantern flies
They're migrating west and all over Pittsburgh I've heard. We've seen 2 or 3 this year, that's it. We noticed last year spiders and bees were attacking them, which we hadn't seen previously. My theory is they have a short lifespan like a cicada and other bugs took a few years to realize they're yummy and not deadly. Once they figured it out, the lantern flies have no counterattack function so they were sitting, well, flies.
Edit: Year, not night. Bugs were swarming the lantern flies last year
