This paper gives an overview of behavioral studies on the color and polarization vision of
the Japanese yellow swallowtail butterfly, Papilio xuthus. We focus on indoor experiments …

Although predation is commonly thought to exert the strongest selective pressure on
coloration in aposematic species, sexual selection may also influence coloration …

Perceptual models of animal vision have greatly contributed to our understanding of animal-
animal and plant-animal communication. The receptor-noise model of color contrasts has …

Polymorphisms are common in the natural world and have played an important role in our
understanding of how selection maintains multiple phenotypes within extant populations …

Intraspecific colour polymorphisms (CPs) present unique opportunities to study fundamental
evolutionary questions, such as the link between ecology and phenotype, mechanisms …

Colour polymorphisms are known to influence receiver behaviour, but how they affect a
receiver's ability to detect and recognize individuals in nature is usually unknown. I …

Many Batesian mimics are considered to be inaccurate copies of their models, including a
number of hoverfly species which appear to be poor mimics of bees and wasps. This …

Colour variation is frequently observed in spiders. Such variation can impact fitness by
affecting the way spiders are perceived by relevant observers such as prey (ie by …

Polymorphisms are useful for studying major evolutionary questions, such as how diversity
arises and is maintained over time. They are a widespread form of biodiversity and take on a …

Conspicuous animal signals are often under conflicting selection, with higher performance
in one fitness component of life history diminishing performance in another component. The …
