In a classic study of perching dragonflies chasing small flying insects, about how often did they catch the prey?

The answer

Olberg, Worthington, and Venator filmed 36 hunts and got a 97% success rate: dragonflies intercept by steering to keep the prey's image still on the eye. Later work shows the rate drops against harder targets, but the headline still holds for easy aerial snacks.

Correct answer: About 97%
