Dragonfly Color Vision

Dragonflies have a unique color vision that surpasses anything ever seen in the animal world. They have four or five different opsins, allowing them to see colors beyond human visual capabilities, such as ultraviolet (UV) light.

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. This enhanced color vision helps dragonflies identify prey, mates, and territories with incredible precision. What appears to us as a plain green leaf might display intricate ultraviolet patterns to a dragonfly, like secret messages written in invisible ink.

The ability to see polarized light adds another dimension to their visual experience. Keywords: dragonfly, opsin, color vision, molecular evolution Abstract Dragonflies are colorful and large. Beds, UK Emperor Dragonfly (Anax imperator) male Beds, UK References Berry, Richard P.

Color vision and color formation in dragonflies. Current Opinion in Insect Science. Dragonflies including damselflies are colorful and large-eyed insects, which show remarkable sexual dimorphism, color transition, and color polymorphism.

Each compound eye is comprised of several thousand elements known as facets or ommatidia. These ommatidia contain light sensitive opsin proteins, thereby functioning as the visual sensing element in the compound eye. But.

Dragonflies possess exceptional color vision that surpasses anything ever seen in the animal world. They have tri-chromatic vision, which means they see light in all species. Vision also plays a role in dragonfly social behaviors, particularly mating.

Their ability to see UV light and a broad spectrum of colors helps them identify potential mates and rivals. Males often display vibrant colors and perform intricate aerial maneuvers to attract females and defend their territories.
