The ommatidia of the butterfly Papilio have a fused and tiered rhabdom. The distal tier of the
rhabdom is made up of four distal photoreceptors (R1–4), whereas the proximal tier is made …

A butterfly Papilio has 5 types of spectral receptors in the compound eye. The spectral
sensitivity of each type peaks in the UV, violet, blue, green, and red wavelengths …

The spectral, angular and polarization sensitivities of photoreceptors in the compound eye of
the monarch butterfly (Danaus plexippus) are examined using electrophysiological methods …

This review outlines our recent studies on the spectral organization of butterfly compound
eyes, with emphasis on the Japanese yellow swallowtail butterfly, Papilio xuthus, which is …

The compound eye of the small white butterfly Pieris rapae crucivora contains three
anatomically distinct types of ommatidia. They differ in pigmentation around the rhabdom …

The distal photoreceptors in the tiered retina of Papilio exhibit different spectral sensitivities.
There are at least two types of short-wavelength sensitive receptors: an ultraviolet receptor …

The compound eye of Pieris rapae crucivora contains ventrally three types of histologically
distinct ommatidia. An ommatidium contains nine photoreceptors, four of which (R1–4) …

The compound eye of the Japanese yellow swallowtail butterfly, Papilio xuthus, consists of
different types of ommatidia characterized by the pigmentation around the rhabdom. About …

The butterfly retina exhibits strong interactions between photoreceptor responses recorded
intracellularly. In general, the receptor which is locally giving the largest response …

The two subspecies of the small white butterfly, the European Pieris rapae rapae and the
Asian P. r. crucivora, differ in wing colouration. Under ultraviolet light, the wings of both male …
