what DAMAGE do the 17 year cicada cause

The seven-year cicadas are loud and annoying, but what damage they really caused. After they’re gone you’ll start to see the branches on your trees turn brown. From what I’ve seen they don’t hit a tree so hard that they actually damage it. But you can definitely see the damage they do. In this video I drive around the neighborhood and show the damage they’ve done and then I’ll get a close-up of some of the ones on my trees.
