When they released the dragonflies, motion-tracking cameras helped them create 3D models of each insect's movements. A Dragonflies ability to manoeuvre in many directions makes them able to out-fly their prey. This maneuver led researchers to investigate how these insects righted themselves when dropped upside-down, since most research on aerial righting has focused on flightless animals such as cats. A carnivorous bird may hunt and catch its own meat, or it could also prey on carrion. In contrast, the researchers found that conscious dragonflies somersaulted backwards to right themselves. They often hunt from a perch ¾ up a tree but also hunt along habitat edges or surprise prey by contour-flying close to the ground. They’re letting birds know that they are really fast and agile and they shouldn’t waste their time trying to catch them.

Debbie Hadley is a science educator with 25 years of experience who has written on science topics for over a decade.

Hadley, Debbie. To catch their prey, dragonflies create a basket with their legs. They need excellent vision to catch unsuspecting insects without being detected as they approach.
