A few years ago I was walking back from my brother in laws house just minding my own business. As I was approaching a tree I saw something drop out of it and on to the ground about 10 feet ahead of me. I walked a few feet further and realised it was a hornet that had attacked a cicada and was in the process of stinging it rendering it paralyzed. It took about 60 seconds from the point of hitting the concrete to when the cicada stopped struggling, I could see the hornet's legs wrapped around the cicada and trying to hold it still. The cicada was huge, 3 and a half inches long. The hornet was about 4 inches. When the cicada quit moving the hornet slowly lifted off and flew away at a greatly refduced speed. My thought of the whole experience was, Damn, that was EVIL. One moment an annoying loud and hated cicada, the next a hornet victim.
