Mimetic wing coloration evolves in butterflies in the context of predator confusion. Unless butterfly eyes have adaptations for discriminating mimetic color variation, mimicry also carries a risk of confusion for the butterflies themselves. Heliconius butterfly eyes, which express recently duplicated ultraviolet (UV) opsins, have such an adaptation. To examine bird and butterfly color vision as sources of selection on butterfly coloration, we studied yellow wing pigmentation in the tribe… 

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.

True UV color vision in a female butterfly with two UV opsins.

TLDR
Results provide some of the first behavioral evidence for female H. erato UV color discrimination in the context of foraging, lending support to the hypothesis that the duplicated UV opsin genes function together in UV color vision.

Sexual dimorphism in the compound eye of Heliconius erato: a nymphalid butterfly with at least five spectral classes of photoreceptor

TLDR
Examination of the spatial pattern of opsin expression and photoreceptor spectral sensitivities in Heliconius erato, a nymphalid with duplicate ultraviolet opsin genes, found that the H. erato compound eye is sexually dimorphic.

The evolution of red color vision is linked to coordinated rhodopsin tuning in lycaenid butterflies

TLDR
A robust heterologous expression system to purify invertebrate rhodopsins is developed, specific amino acid changes responsible for adaptive spectral tuning are identified, and molecular variation in invertebrates opsins underlie wavelength sensitivity shifts that enhance visual perception are pinpointed.

Genetic switch in UV response of mimicry-related pale-yellow colors in Batesian mimic butterfly, Papilio polytes

TLDR
It is revealed that dsx (H) switched the pale-yellow colors from UV-excited fluorescent type (nonmimetic) to UV-reflecting type (mimetics), by repressing the papiliochrome II synthesis genes and nanostructural changes in wing scales.

Sex-limited diversification of the eye in Heliconius butterflies

TLDR
It is hypothesized that female eyes are optimized for a dimorphic behavior such as oviposition, while male eyes adapt to other selective pressures such as the local light environment.

Opsin Evolution and Sensory Physiology of the Compound Eye in Heliconius Butterflies

TLDR
Novel UV photoreceptor subtypes evolved in Heliconius via opsin gene duplication, and subsequent varying selection pressures have likely caused the increased diversity of retinal mosaics within the genus, including three unique forms of sexual dimorphism and multiple independent pseudogenizations of UVRh2.

The appearance of mimetic Heliconius butterflies to predators and conspecifics

TLDR
It is shown that visual signals can act to both reduce the cost of confusion in courtship and maintain the advantages of mimicry.

Longwing (Heliconius) butterflies combine a restricted set of pigmentary and structural coloration mechanisms

TLDR
This work investigates the coloration mechanisms among several species of Heliconius by applying scanning electron microscopy, (micro)spectrophotometry, and imaging scatterometry and identifies seven kinds of colored scales within Heliconians whose coloration is derived from pigments, nanostructures or both.

The influence of ultraviolet reflectance differs between conspicuous aposematic signals in neotropical butterflies and poison frogs

TLDR
The results support the notion that although UV reflectance is associated with intraspecific communication in butterflies, it appears to be nonfunctional in frogs, and highlight that one should be careful when assigning a selection‐based benefit to the presence ofUV reflectance.

Positive selection of a duplicated UV-sensitive visual pigment coincides with wing pigment evolution in Heliconius butterflies

TLDR
Functional diversification of the UV-sensitive visual pigments may help explain why the yellow wing pigments of Heliconius are so colorful in the UV range compared to the yellow pigment of close relatives lacking the UV opsin duplicate.

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.

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.

A butterfly eye's view of birds

TLDR
Considering the similarities between the two taxa, it is surprising that the eyes of birds are not more diverse, and additional taxonomic sampling of birds may help clarify this mystery.

Sexual Dimorphism of Short-Wavelength Photoreceptors in the Small White Butterfly, Pieris rapae crucivora

TLDR
The eyes of the female small white butterfly, Pieris rapae crucivora, are furnished with three classes of short-wavelength photoreceptors, with sensitivity peaks in the ultraviolet (UV), violet, and blue (B) wavelength range, which are termed PrUV, PrV, and PrB.

Colour pattern evolution in butterflies: a phylogenetic analysis of structural ultraviolet and melanic markings in North American sulphurs

TLDR
Analysis of the phylogenetic distribution of two elements of male colour pattern – UV reflectance and melanic markings – in North American sulphur butterflies sheds interesting light on the evolution of structural coloration in this group and adds strength to the idea that brilliant male coloration is principally of sexually selected origin.

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.

Tetrachromacy in a butterfly that has eight varieties of spectral receptors

TLDR
The first evidence of tetrachromacy among invertebrates is presented, and the profile of the Δλ function of Papilio can be best reproduced by postulating that the UV, blue (narrow-band and wide-band), green (double-peaked) and red classes are involved in foraging.

Color discrimination in the red range with only one long-wavelength sensitive opsin

TLDR
It is shown here, through behavioral experiments, that the nymphalid butterfly Heliconius erato, although it expresses short and medium wavelength opsins and only one long wavelength opsin, discriminates colors in the long-wavelength range, whereas another nymphatic, Vanessa atalanta, despite having color vision, is unable to do so.

Color vision and learning in the monarch butterfly, Danaus plexippus (Nymphalidae)

TLDR
The results demonstrate that monarchs are proficient and flexible color learners; these capabilities should allow them to respond rapidly to changing nectar availabilities as they travel over migratory routes, across both space and time.
