Yeah, but it's patchy. There's a couple big trees down the block from my house where each one has hundreds of those exoskeletons on them, there's literally a carpet of the exoskeletons around them. While my backyard has 6 trees and I've yet to notice even one out there. I've seen a few dozen live ones, but all seem to be freshly matured. Most of them didn't have their wings fully unfolded yet, and haven't seen a single one flying or heard a single one calling.
