This is a video in the field showing a dragonfly on the hunt for prey — shown at normal speed and then in slow motion. The dragonfly hovers while it searches for prey, moving its head and then repositioning its body, ready to pursue a target. When a target is identified (in this case a small fly), the dragonfly locks on and ignores all other potential targets. It swoops up and catches its prey.
