The iridescent features of the butterfly species Apatura iris (Linnaeus, 1758) and A. ilia (Denis & Schiffermüller, 1775) were studied. We recognized the structural color of scales only on the dorsal side of both the fore and hind wings of males of both of the aforementioned butterfly species. The scale dimensions and microstructure were analyzed by a scanning electron microscope (SEM) and transmission electron microscope (TEM). The optical properties were measured and it was found that the… 
Micro‐ and nanostructures of iridescent wing scales in purple emperor butterflies (Lepidoptera: Apatura ilia and A. iris)
The scales of the analyzed species resemble the scales of tropical Morpho butterflies, particularly the type I scales of A. ilia.
Coloration principles of the Great purple emperor butterfly (Sasakia charonda)
The dorsal wings of male Sasakia charonda butterflies display a striking blue iridescent coloration, which is accentuated by white, orange-yellow and red spots, as well as by brown margins. The
The lesser purple emperor butterfly, Apatura ilia: from mimesis to biomimetics.
By selecting various effect pigments, and using the lesser purple emperor butterfly, Apatura ilia, as exemplar, this work has accurately mimicked the butterfly's iridescence in art.
Coloration and structure of Taiwanese bronze scarab (Anomala expansa)
The structure and optical properties of the elytra of Taiwanese bronze scarabs (Anomala expansa) were investigated. The elytron is composed by a scale-like texture on the surface and a repeated
Optical Lattices on Wings of Apatura Butterflies
ABSTRACT: Optical microscopy of scales from the wings of the male butterfly Apatura ilia reveals parallel fibers with a spacing of about 710 nm. These fibers, together with tiny transverse grooves,
Detailed experimental characterization of reflectance spectra of Sasakia charonda butterfly using multispectral optical imaging
Abstract. A multispectral acquisition system to examine the bidirectional reflectance distribution function of structurally colored biological materials in the visible range is presented. We focus on
Localization of light in photonic crystals of biological origin
Structures similar to those found on butterfly wings were produced holographically on thin layers of dichromated pullulan. Light propagation and scattering is studied in these nanometre periodic
Scattering of ultraviolet light by avian eggshells.
Simulations of the UV response of this porous structure using Mie scattering theory as well as an effective approach accounting for multiple scattering indicate that these pores are responsible for the backscattering peaks observed in the UV range, in the case of beige hen eggshells.
Origin and functions of iridescent colours in hummingbirds
It is found that the structures producing iridescence in hummingbirds are way more diverse than what the authors previously thought, and this suggests a possible role of the environment in the evolution of these colours, possibly for camouflage against predators.
Detailed simulation of structural color generation inspired by the Morpho butterfly.
This paper presents an extensive simulation of the reflectance spectra of a simplified 2D Morpho butterfly wing model by utilizing the finite-difference time-domain method and finds that the wavelength of the reflection maximum is mainly set by the lateral dimensions of the structures.


Wing Colors of Chrysozephyrus Butterflies (Lepidoptera;Lycaenidae): Ultraviolet Reflection by Males
Wing colors of the four species of Chrysozephyrus butterflies were analyzed by a spectrophotometer. As the dorsal wing surface of males showed a strong reflectance when the specimen was tilted,
Ultraviolet Reflection of a Male Butterfly: Interference Color Caused by Thin-Layer Elaboration of Wing Scales
The male of the butterfly Eurema lisa, like many other members of the family Pieridae, reflect ultraviolet light, but the female lacks such scales and is consequently nonreflectant.
Structural colour in Lepidoptera
Microstructure and structural color in wing scales of butterfly Thaumantis diores
The butterfly Thaumantis diores is a species in the Northeast of China. There are two kinds of scales on its wings, which overlap like roof tiles and completely cover the membrane. The SEM results
Quantified interference and diffraction in single Morpho butterfly scales
Brilliant iridescent colouring in male butterflies enables long–range conspecific communication and it has long been accepted that microstructures, rather than pigments, are responsible for this
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.
Structurally assisted blackness in butterfly scales
The optical absorption associated with black wing regions on the butterfly Papilio ulysses is quantified and it is found that the nano–structure of the wing scales of these regions contributes significantly to their black appearance.
Far field scattering pattern of differently structured butterfly scales
The angular and spectral reflectance of single scales of five different butterfly species was measured and related to the scale anatomy. The scales of the pierids Pieris rapae and Delias nigrina
