Dragonfly Eye Color

The dorsal eyes of Sympetrum (below), and other dragonflies, contain yellow screening pigments in combination with a very high frequency of blue receptors, as well as a fovea. Consequently, dragonflies possess superior color vision, described as ultra-multicolour. Their compound eyes, occupying nearly their entire head, provide a unique field of vision, enabling them to see in all directions simultaneously.

Each dragonfly eye also contains simpler lenses, contributing to their remarkable visual capability. As a result, these dragonfly species probably also have a corresponding decrease in overall color perception. Dragonflies (and bees) have the largest compound eyes of any insect; each containing up to 30,000 facets, and the eyes cover most of the insect's head, resembling a motorcycle helmet.

Color's Role in Mating and Territory The most significant driver of the dragonfly's brilliant coloration is its role as a visual signal in reproductive behavior. Male dragonflies, in particular, use their vibrant colors to attract mates and establish dominance over rivals. Eye of the Dragonfly Fun fact: The hexagon is the most common shape in nature.

The hexagons in this image are in the eye of a dragonfly. Each hexagonal rod, called an ommatidium, contains major structures that have analogues/counterparts in our own eyes. Keywords: dragonfly, opsin, color vision, molecular evolution Abstract Dragonflies are colorful and large.

In this article, I aim to introduce the genetic basis of the color polymorphisms, and review recent progress in molecular mechanisms underlying the color vision and color formation in dragonflies. Their massive globular eyes should have been a clue. It turns out dragonflies have souped-up colour vision that's better than anything ever seen in the animal world.

We humans have what's. Blue is one of the most common dragonfly colors, visible on the body, eyes, and wings. Some blue species include the blue emperor dragonfly and the blue dasher.
