Lantern flies aren’t as destructive as we thought. What changed?

In Pennsylvania, we all know what to do when we see a spotted lantern fly. Kill it, immediately, with no hesitation. But, according to a recent Penn State study, hardwood trees such as maple, willow and birch may be less vulnerable to the flies than first thought. What changed? Are we totally in the clear? And, is this just the beginning? We dissect the study with Dr. Christopher Tipping, the chair and professor in the department of biology at Delaware Valley University. He tells us what this new information means and what to look for moving forward.
