The dreaded copper mouthed gonzo constrictor.
We have a huge post oak in the middle of the yard at my property in central Texas. Whenever there is a mass hatching of the local cicada, the nymphs come out of ground at dusk, crawl up the side of the tree trunk to shed their exoskeletons, deploy their wings to fly off when they dry. A large number of copper heads also come out and grab as many bugs as they can off the side of the tree. We just sit on the screen porch and watch with the dull glow of the porch light illuminating the scene. Kind of cool.
