The striking color patterns of butterflies and birds have long interested biologists. But how these animals see color is less well understood. Opsins are the protein components of the visual pigments of the eye. Color vision has evolved in butterflies through opsin gene duplications, through positive selection at individual opsin loci, and by the use of filtering pigments. By contrast, birds have retained the same opsin complement present in early‐jawed vertebrates, and their visual system has… Expand
The Colorful Visual World of Butterflies
TLDR
Butterflies have long inspired evolutionary biologists with the striking diversity of their wing colors, and lineage-specific opsin duplications and expression of filtering pigments have facilitated the evolution of sexually dimorphic butterfly eyes. Expand
Contrasting modes of evolution of the visual pigments in Heliconius butterflies.
TLDR
Examining the UV opsin genes of passion-vine butterflies found both physiological and statistical evidence consistent with purifying selection on UVRh1, BRh, and LWRh along the branch leading to the common ancestor of Heliconius, underscore the utility of combining molecular and physiological experiments in a comparative context for strengthening evidence for adaptive evolution at the molecular level.

UV Photoreceptors and UV-Yellow Wing Pigments in Heliconius Butterflies Allow a Color Signal to Serve both Mimicry and Intraspecific Communication
TLDR
These results are the best available evidence for the correlated evolution of a color signal and color vision and suggest that predator visual systems are error prone in the context of mimicry. Expand
Opsin clines in butterflies suggest novel roles for insect photopigments.
TLDR
The results suggest that opsin diversification in this butterfly is more consistent with natural selection unrelated to spectral tuning, and the possibility that insect opsins might have important, yet-to-be elucidated, adaptive functions in mediating animal responses to abiotic factors, such as temperature or photoperiod is discussed. Expand
Extrinsic Versus Intrinsic Control of Avian Communication Based on Colorful Plumage Porphyrins
TLDR
Synthesis of patterns indicated that VS visual systems always evolved prior to colorful plumage porphyrins, suggesting a sensory bias for plumage pigments based on signal-receptor alignment. Expand
Butterfly dichromatism primarily evolved via Darwin's, not Wallace's, model
TLDR
It is shown that male coloration evolved faster than female coloration, especially in strongly dichromatic clades, with male contribution to changes in dichromatism roughly twice that of females. Expand
Ultraviolet and yellow reflectance but not fluorescence is important for visual discrimination of conspecifics by Heliconius erato
TLDR
The results suggest that the use of 3-OHK pigmentation instead of ancestral yellow was driven by sexual selection rather than predation, which predators find similarly aposematic compared with the ancestral yellow pigments used by non-Heliconius mimics. Expand
Limited variation in visual sensitivity among bowerbird species suggests that there is no link between spectral tuning and variation in display colouration
TLDR
Spect spectral sensitivity among bowerbird species that occupy different visual habitats and are highly diverged in plumage and decoration colour displays is compared, suggesting that bowerbirds may represent a transitional stage in the evolution from the ancestral violet-sensitive- to the derived ultraviolet- sensitive-type short-wavelength-sensitive1-based visual system found in younger passerine lineages. Expand
Complex dynamics underlie the evolution of imperfect wing pattern convergence in butterflies
TLDR
Although these data reveal the first evidence for protection from avian predators by the supposed toxic, Rubiaceae‐feeding Adelpha species, it is concluded that imprecise mimetic patterns have high costs for Batesian mimics in the tropics. Expand
From spectral information to animal colour vision: experiments and concepts

TLDR
The capabilities of di- and trichromatic vision are compared, and why some animals have more than three spectral types of receptors are asked, and awareness of colour and colour qualia cannot be easily tested in animals. Expand

TLDR
A model for the patterning of the ancestral butterfly eye that is most closely aligned with the nymphalid eye is proposed, which underwent an adaptive expansion based on lineage-specific B and LW opsin gene multiplications and on alterations in the spatial expression of opsins within the eye. Expand
Adaptive evolution of color vision as seen through the eyes of butterflies
TLDR
The data show that some of the same amino acid sites are under positive selection in the photopigments of both butterflies and primates, spanning an evolutionary distance >500 million years. Expand
Complex distribution of avian color vision systems revealed by sequencing the SWS1 opsin from total DNA.
TLDR
The data support VS as the ancestral state in birds and show that UVS has evolved independently at least four times, indicating that interactions between predators and prey may explain the presence of UVS in Laridae and Passeriformes. Expand
Evolution of color and vision of butterflies.
TLDR
The corneal nipple array and the tapetum, optical structures that many but not all butterflies share with moths, suggest that moths are ancestral to butterflies, in agreement with molecular phylogeny. Expand
Molecular Evolution of Arthropod Color Vision Deduced from Multiple Opsin Genes of Jumping Spiders
TLDR
Phylogenetic analyses of jumping spider opsins revealed a birth and death process of color vision evolution in the arthropod lineage, and sequence comparison between jumping spider Rh3 and the shorter wavelength-sensitive opsins of insects predicted that an opsin of the ancestralArthropod had the lysine residue responsible for UV sensitivity. Expand
Pteropsin: a vertebrate-like non-visual opsin expressed in the honey bee brain.
TLDR
Insect pteropsin might be orthologous to a ciliary opsin recently described from the annelid Platynereis, and therefore represents the presence of this vertebrate-like light-detecting system in insects. Expand
The lycaenid butterfly Polyommatus icarus uses a duplicated blue opsin to see green
TLDR
It is demonstrated that the lycaenid Polyommatus icarus uses its duplicate blue opsin in conjunction with its long-wavelength (LW) opsin, LWRh, to see color in the green part of the light spectrum extending up to 560 nm, which suggests that lateral filtering pigments may not always influence color vision in insects. Expand
Ancient colour vision: multiple opsin genes in the ancestral vertebrates
TLDR
The genetic complement of visual pigment opsins in G. australis must have originated very early in vertebrate evolution, prior to the separation of the jawed and jawless vertebrate lineages, and thereby provided the genetic basis for colour vision in all vertebrate species. Expand
Beauty in the eye of the beholder: the two blue opsins of lycaenid butterflies and the opsin gene-driven evolution of sexually dimorphic eyes
TLDR
The butterfly Lycaena rubidus has evolved sexually dimorphic eyes due to changes in the regulation of opsin expression patterns to match the contrasting life histories of males and females, and this novel blue opsin gene duplication may help explain the blueness of blue lycaenid butterflies. Expand
Avian Visual Pigments: Characteristics, Spectral Tuning, and Evolution
TLDR
In birds, UVS visual pigments have re‐evolved from an ancestral avian VS pigment by using a novel molecular mechanism not seen in other vertebrate classes, which has occurred independently in four of the 14 avian orders examined to date. Expand
