You learn something new about nature all the time when you live by a river. This time it's about dragonfly behavior. Some of the dragonflies you'll see in this video have numbers on their wings. They were part of a Harvard science project to observe how dragonflies capture prey. The dragonfly animation in the video was made with parts left over from a dragonfly swarm like the current ones around Janesville.
