Do dragonflies see 360?

Dragonfly vision is thought to be like slow motion for humans. Dragonflies see faster than we do; they see around 200 images per second. Dragonfly can see in all 360 degrees around it and nearly 80 percent of the insect's brain is dedicated to its sight.

How do dragonflies perceive time?

by Roaring Earth Staff

The Dragonfly is able to see the world in a completely different way than how we perceive it. With a super-fast reaction time, this insect effectively sees time in what we would call slow-motion. Because they have a reaction time far faster than us, they can process information MUCH faster.
