A new paper found male dragonflies defending breeding territory rely on simple rules to hold a tactical position during mid-air dogfights, rather than using the pursuit patterns seen in hunting.
Using two synchronized cameras, researchers reconstructed 102 male-on-male 3D flight trajectories and compared them with nine prey-interception flights to model the insects’ guidance behavior.
Those reconstructions showed hunting dragonflies typically approach prey from below against the sky, while territorial clashes produce more convoluted paths against foliage or ground backgrounds.
The authors say the mutual-pursuit rules resemble human fighter-pilot tactics and could help designers build drones that navigate with simpler vision-based guidance instead of heavier computation.
