Description
This Tiger dragon fly is in my garden after I safe her from my garage, she is happy to sit there and it looks like she rolling her eyes at me ! The swirls are amazing, I didn't really see it properly until I seen the photo ! I live at Northern beaches in Sydney.
Their massive globular eyes should have been a clue. It turns out dragonflies have souped-up colour vision thats better than anything ever seen in the animal world.
We humans have whats known as tri-chromatic vision, which means we see colours as a combination of red, blue and green. This is thanks to three different types of light-sensitive proteins in our eyes, called opsins. We are not alone: di-, tri- and tetra-chromatic vision is de rigueur in the animal world, from mammals to birds and insects.
A study of 12 dragonfly species has found that each one has no fewer than 11, and some a whopping 30, different visual opsins.
Other studies have found that dragonflies can see ultraviolet on top of blue, green and red. And it is thought that they can recognise polarised light coming off reflective surfaces like water. Its likely that they have better colour discrimination than humans, says Futahashi.
