SUMMARY For nearly 80 years, the non-iridescent, blue, integumentary structural colours of dragonflies and damselflies (Odonata) have been attributed to incoherent Tyndall or Rayleigh scattering. We investigated the production of the integumentary structural colours of a damselfly – the familiar bluet, Enallagma civile (Coenagrionidae) – and a dragonfly– the common green darner, Anax junius (Aeshnidae) – using fibre optic spectrophotometry and transmission electron microscopy (TEM). The…

Anatomically diverse butterfly scales all produce structural colours by coherent scattering
The 2D Fourier analyses of TEMs of colour producing butterfly scales document that all species are appropriately nanostructured to produce visible colours by coherent scattering, i.e. differential interference and reinforcement of scattered, visible wavelengths.
Pterin-pigmented nanospheres create the colours of the polymorphic damselfly Ischnura elegans
This work quantifies the colour development of all morphs of I. elegans and investigates colour formation by combining anatomical data and reflectance spectra with optical finite-difference time-domain simulations.
Wrinkles enhance the diffuse reflection from the dragonfly Rhyothemis resplendens
This property enhances the visibility of the static wing over a broader angle range than is normally associated with a smooth multilayer, thereby markedly increasing its conspicuousness.
Pterin pigments amplify iridescent ultraviolet signal in males of the orange sulphur butterfly, Colias eurytheme
Spectrophotometric analyses of the wings before and after pterin removal show that pterins both depress the amplitude of UV iridescence and suppress a diffuse UV reflectance that emanates from the scales, and this latter effect enhances the directionality and spectral purity of theIridescence.
Structural coloration in nature
Nature's color has three main sources: pigments, structural colors and bioluminescence. Structural color is a special one, which is the color produced by micro- or nano-structures, and is bright and
Gold bugs and beyond: a review of iridescence and structural colour mechanisms in beetles (Coleoptera)
An overview of iridescence mechanisms observed in Coleoptera is provided, along with discussion of the putative functions and evolutionary pathways by which iridescent has repeatedly arisen in beetles.
Fourier Blues: Structural Coloration of Biological Tissues
The focus of this article is, in particular, on a truly fascinating manifestation of Fourier analysis and synthesis in nature, which provides a way to explain coloration phenomena that are of interest in behavioral and evolutionary biology.
Exaggeration and suppression of iridescence: the evolution of two-dimensional butterfly structural colours
This study optically characterize examples of all three types of multi-layer structure, as found in 10 species, and considers the phylogeny of the butterflies, and is able to relate the optical properties of the structures to their evolutionary development.


Coherent light scattering by nanostructured collagen arrays in the caruncles of the malagasy asities (Eurylaimidae: aves)
Results confirm that the nanostructure of the collagen arrays determines the colours that are coherently scattered by these tissues, and all the tissues are substantially nanostructured at the appropriate spatial scale to scatter visible light coherently.
Two-dimensional Fourier analysis of the spongy medullary keratin of structurally coloured feather barbs
Two–dimensional (2D) discrete Fourier analyses of the spatial variation in refractive index of the spongy medullary keratin from four different colours of structurally coloured feather barbs from three species of bird indicate that the spongey medully keratin is a nanostructured tissue that functions as an array of coherent scatterers.
Structural colouration of avian skin: convergent evolution of coherently scattering dermal collagen arrays
Investigation of the colour, anatomy, nanostructure and biophysics of structurally coloured skin, ramphotheca and podotheca from 31 species of birds from 17 families in 10 orders from across Aves finds some yellow and orange skin colours are produced with a combination of structural and pigmentary mechanisms.
Structural colouration of mammalian skin: convergent evolution of coherently scattering dermal collagen arrays
The Fourier power spectra and the observed reflectance spectra falsify assumptions and predictions of the incoherent, Rayleigh scattering hypothesis and reveal a substantial nanostructure of the appropriate spatial frequency to produce the observed blue hues by coherent scattering alone.
Two-dimensional Fourier analysis of transmission electron micrographs of the medullary keratin of UV-colored feather barbs of the Blue Whistling Thrush demonstrates that the Myiophonus medullaries keratin is ordered at the appropriately nanoscale to produce the observed UV hues by coherent scattering.
Coherent light scattering by blue feather barbs
The structural colours of avian feather barbs are created by the scattering of light from the spongy matrix of keratin and air in the medullary layer of the barbs,. However, the precise physical
A Fourier Tool for the Analysis of Coherent Light Scattering by Bio-Optical Nanostructures1
The applications of the Fourier tool have falsified the century old hypothesis that the non-iridescent structural colors of avian feather barbs and skin are produced by incoherent Rayleigh or Tyndall scattering and provided a single method for the analysis of coherent scattering by a diversity of nanostructural classes.
Light and color on the wing: structural colors in butterflies and moths.
All butterfly and moth scales share the same basic architecture, but various elements of this architecture are particularly complex in those scales that exhibit structural colors, which represents a particularly striking example of precision in biological pattern formation.
Phylogenetic analysis of higher‐level relationships of Odonata
Abstract. This is the most comprehensive analysis of higher‐level relationships in Odonata conducted thus far. The analysis was based on a detailed study of the skeletal morphology and wing venation
