According to the latest research, scientists have discovered that dragonflies hunt much more like humans than originally thought. In fact, instead of reacting to their prey’s movements, the dragonflies try to anticipate what their prey will do ahead of time. According to the Washing Post, this new finding can help us learn how humans use these same neurological calculations to track prey.
The study was based on the theory that the brain reacts based on a stimulus. This shows that something would have to happen for the muscles in the brain to start working. Anthony Leonardo contradicts this theory by relating it to a human in which they must make calculations to catch a ball ahead of time. Flies on the other hand would see something and then react to it by flying away. After studying dragonflies, researchers now know that the dragonflies exhibit behaviors more like humans than flies when reacting to stimulus.
In order to observe how dragonflies react or handle their prey, they used both fake and real prey to test the dragonflies. Upon studying these creatures, they found that the dragonflies were very calculated and predictive. The dragonflies actually attack their prey from below using a calculated path. By doing this, the dragonfly can watch the prey better while still directing its body.
In order to navigate over to the prey while still focusing on it, the dragonflies submit a signal from the brain to the wings. This allows the animal to steer while also keeping its head a certain way to help it focus on the prey and predict the prey’s path. To better relate this to a human’s movements, they used the idea of a human picking up coffee. Further study is expected to be done between dragonflies and humans.
