So, if it’s so difficult to be blue, why bother - well we all like to be different don’t we?
They are notable for the presence of blue pigments in their wings, as opposed to blue created by physical structures. Most other species get their blue coloration from a process called coherent scattering, in which scattered light waves interfere to create a blue color.
Nessaea aglaura, the common olivewing,[2] northern nessaea or Aglaura olivewing, is a species of butterfly of the family Nymphalidae. However while blue roses and carnations still evade us a team in Japan has been able to produce the first truly blue Chrysanthemum.
Many pigments in animals come from the food they eat.
Nessaea obrinus, the obrina olivewing, is a species of butterfly of the family Nymphalidae.It is found from Colombia and the Guianas to the mouth of the Amazon and south to central Bolivia and Mato Grosso in Brazil, extending to northern Argentina.
It is found from Colombia and the Guianas to the mouth of the Amazon and south Neotropical Nymphalidae VII. It is found in evergreen tropical forest and in semi-deciduous tropical forest.

[5] Other butterflies in Graphium and Papilio (specifically P. phorcas and P. weiskei) use the blue pigments phorcabilin and sarpedobilin.
The larvae feed on Alchornea costaricensis and Plukenetia volubilis.
OBRINA OLIVEWING (Nessaea obrinus) The obrina olivewing, similar to the common olivewing, is a species of butterfly of the family Nymphalidae. The obrina olivewing butterfly is the only known animal to produce a true blue pigmentNotafly (CC BY-SA 3.0). It is found from Colombia and the Guianas to the mouth of the Amazon and south to central Bolivia and Mato Grosso in Brazil, extending to northern Argentina.[2]. We like blue, but it was a difficult colour to obtain until relatively recently when synthetic dyes allowed any colour to be made. Adults of subspecies faventia are on wing year round, but mainly from June to October and adults of subspecies lesoudieri are on wing year round, with no observed peak of abundance. The most commonly used are the red pigments, called anthocyanins, and whose appearance can be changed by varying acidity.
If the scales were shaped differently, the blue colour would vanish. Whilst blue might be a favourite colour of us humans – a YouGov poll lists blue as the favourite colour for almost every country on earth.
It is found from Mexico to Panama, Ecuador, Venezuela and Colombia. SA 5005 AUSTRALIA, Future student enquiriesCurrent student enquiriesWebsite feedback, Open Day: Biomedical Science & Biotechnology, Honours in Science - Expression of Interest.
Blue on any animal (including humans' blue eyes) is due to some kind of light reflection of this type. [3] All the other species of Nessaea get their blue coloration from the pigment pterobilin. If you’re a plant, having different coloured flowers can help attract a unique pollinator. Obrina Olivewing butterflies are very unusual because they are one of the few animals with actual blue pigment.

And recent work has shown that the colour preferences of pollinating bees has probably driven the diverse range of flower colours we see today, including blue. Instead of pigment mixing or alteration, blue is achieved in many animals by making structures that change the wavelength of light. So why is that?
If the wing scales of the Blue morpho butterfly were shaped differently their blue colour would vanish.Charles Patrick Ewing (CC BY 2.0). The only exception is the obrina olivewing butterfly, which is the only known animal in nature that produces blue pigment.
Part of the reason is that there isn’t really a true blue colour or pigment in nature and both plants and animals have to perform tricks of the light to appear blue.
It is found from Mexico to Panama, Ecuador, Venezuela and Colombia.
The main reason for this has to do with the physics of light. The obrina olivewing butterfly is the only known animal to produce a true blue pigment Notafly (CC BY-SA 3.0) Why bother? Clicking the Organism name shows the images, and pointing the Organism name shows the tooltip with three links at the left-top corner.
Each feather is made up of light-scattering, microscopic beads spaced in a way that every wavelength of light is cancelled out except blue – think noise cancelling headphones here.
But as we heard above, since there is no true blue pigment in plants, animals can’t turn blue through food. So, if it’s so difficult to be blue, why bother - well we all like to be different don’t we?
The most common plant pigment is green chlorophyll, so plants appear green because chlorophyll doesn’t absorb, but rather reflects, green light.
Picasso’s blue period) and blue has always been associated with privilege – think royal blue. It is found in evergreen tropical forest and in semi-deciduous tropical forest.[3].
Sea of blue nemophila plantsImage by Pixabay. Adults are on wing nearly year round. [4] Pterobilin also provides blue for Graphium agamemnon, G. antiphates, G. doson, and G. Adults of subspecies obrinus are on wing in January and from July to November. Although blue flowers are rare in plants, almost no plant has blue leaves – except a handful of plants found on the floor of tropical rainforests. View the original article. Blue birds, such as the blue jay, get their colour through a similar, but slightly different process.
But when it comes to nature, blue is very rare. Blue will continue to remain a rarity in nature.
Nessaea aglaura, the common olivewing,[2] northern nessaea or Aglaura olivewing, is a species of butterfly of the family Nymphalidae. Today blue flowers are still highly prized, and many have been trying to grow and breed the perfect blue bloom. +61 8 8313 5673faculty.sciences@adelaide.edu.au, THE UNIVERSITY OF ADELAIDE Revision of Nessaea, https://en.wikipedia.org/w/index.php?title=Nessaea_aglaura&oldid=846469791, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 June 2018, at 23:45.
These alterations, combined with reflected light, can create some spectacular results: delphinums, plumbago, bluebells, hydrangeas, dayflowers, morning glories and cornflowers. Animals have a much harder time turning blue.
Click on the links or butterfly Blue is a very prominent colour on earth.
So, flamingos are pink because of the dye they get from eating their favourite food – shrimp, and the golden colour of goldfish comes for their food.
sarpedon.
Poison dart frogs warn off predators with their brilliant blue bodiesCliff (CC BY 2.0). Plants however like blue light as it has more energy than any other light in the visible spectrum. The Obrina Olivewing is a species of butterfly of the Nymphalidae family. So, if you have blue leaves you are reflecting the highest energy light and relegating yourself to using only poorer quality light that ultimately limits your growth.
Artists hankered after blue (e.g.
The only exception in nature is the obrina olivewing butterfly, which is the only known animal to produce a true blue pigment.
For animals, eye-popping blue colours, in anything from butterflies to frogs to parrots, is useful for getting attention – either good – attracting a mate (like the dance of the courting birds of paradise) or bad – warning off predators (poison dart frog).
All butterfly specimens for sale are farm raised butterflies from around the world that died from natural causes.
Less than 1 in 10 plants have blue flowers and far fewer animals are blue.
Not a good strategy and so why most plants avoid it. For example, the blue morpho butterfly gets its colour from the fact that its wing scales are shaped in ridges that causes light to bend in such a way that the only wavelength of light it reflects is blue. Pigments appear the colour of the light they don’t absorb, but instead reflect.
