I am linking to a detailed explanation of how dragonflies are able to detect and then intercept other flying insects. Researchers at Howard Hughes Research Institute installed tiny reflectors on dragonflies to track their body movements while hunting. Those reflectors were then followed by special cameras that send that tracking data to computers for analysis. They found that dragonflies are good hunters because of their ability to anticipate the movements of their prey and calculate accurate interception routes. I found it interesting that dragonflies approach their targets from below to avoid detection. Jet fighter pilots sometimes use that same technique. These behaviors are far more complex than expected in an invertebrate and have implications for the study of human behavior.
