Tetrachromacy in a butterfly that has eight varieties of spectral receptors
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 Papilio isExpand

Influence of Lactic Acid Bacteria on Longevity of Caenorhabditis elegans and Host Defense against Salmonella enterica Serovar Enteritidis
ABSTRACT This study aimed to develop a convenient model to investigate the senescence of host defenses and the influence of food and nutrition. A small soil nematode, Caenorhabditis elegans, wasExpand

Polarisation-dependent colour vision in Papilio butterflies.
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 orientations. WeExpand

Sexual Dimorphism of Short-Wavelength Photoreceptors in the Small White Butterfly, Pieris rapae crucivora
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) (λmax = 360Expand

Two visual pigments in a single photoreceptor cell: identification and histological localization of three mRNAs encoding visual pigment opsins in the retina of the butterfly Papilio xuthus.
This paper describes the localization of newly identified visual pigment opsins in the tiered retina of the Japanese yellow swallowtail Papilio xuthus. We first cloned three cDNAs encoding visualExpand

Light on the moth-eye corneal nipple array of butterflies
The outer surface of the facet lenses in the compound eyes of moths consists of an array of excessive cuticular protuberances, termed corneal nipples. We have investigated the moth-eye corneal nippleExpand

Associative visual learning, color discrimination, and chromatic adaptation in the harnessed honeybee Apis mellifera L.
We studied associative visual learning in harnessed honeybees trained with monochromatic lights associated with a reward of sucrose solution delivered to the antennae and proboscis, to elicit theExpand

Depth Perception from Image Defocus in a Jumping Spider
A Good Judge of Distance Jumping spiders actively pursue their prey, often jumping relatively long distances in order to catch them. Such feats require accurate depth perception. Nagata et al. (p.Expand

Evolution of color and vision of butterflies.
Butterfly eyes consist of three types of ommatidia, which are more or less randomly arranged in a spatially regular lattice. The corneal nipple array and the tapetum, optical structures that many butExpand
