Stomatopods (mantis shrimps) possess apposition compound eyes that contain more
photoreceptor types than any other animal described. This has been achieved by sub …

Many insect species have darkly coloured eyes, but distinct colours or patterns are
frequently featured. A number of exemplary cases of flies and butterflies are discussed to …

This paper presents the first evidence of tetrachromacy among invertebrates. The Japanese
yellow swallowtail butterfly, Papilio xuthus, uses colour vision when foraging. The retina of …

Connectomics has become a standard neuroscience methodology in a few model animals,
1 with the visual system being a popular target of study. 2–5 Combining connectomics with …

This paper demonstrates that foraging summer-form females of the Japanese yellow
swallowtail butterfly Papilio xuthus have colour vision. The butterflies were trained to feed on …

The spectral information available to an animal's visual system depends both on the
wavelengths reaching its outer segments and the visual pigments contained within them …

Swallowtail butterflies of the species Papilio aegeus oviposit on the leaves of Rutaceae
plants in Australia. They possess receptor types with sensitivity peaks around 390 nm (violet …

The compound eye of the butterfly Papilio xuthus consists of three different types of
ommatidia, each containing nine photoreceptor cells (R1–R9). We have found previously …

Butterflies of the genus Papilio have polarisation-sensitive photoreceptors in all regions of
the eye, and different spectral types of receptor are sensitive to different e-vector …

Surveys of spectral sensitivities, visual pigment spectra, and opsin gene sequences have
indicated that all butterfly eyes contain ultraviolet‐, blue‐, and green‐sensitive rhodopsins …
