Dragonflies represent an ancient lineage of visual predators, which last shared a common
ancestor with insect groups such as dipteran flies in the early Devonian, 406 million years …

Amacrine cells in the external plexiform layer of the fly's lamina have been intracellulary
recorded and dye-filled for the first time. The recordings demonstrate that like the lamina's …

Retained larval eyes (stemmata) were studied in the imagines of three species of
Trichoptera: Phrygania grandis, Agrypnia varia, and Trichostegia minor. At the light …

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 …

The eye of the Glacial Apollo butterfly, Parnassius glacialis, a 'living fossil'species of the
family Papilionidae, contains three types of spectrally heterogeneous ommatidia. Electron …

The visual system of insects provides an excellent model to study processes of transduction
and transmission of photic information, synaptogenesis, synaptic plasticity, and wiring …

Jin-Tun Lin, Pi-Chi Hwang and Li-Chu Tung (2002) Visual organization and spectral
sensitivity of larval eyes in the moth Trabala vishnou Lefebur (Lepidoptera: Lasiocampidae) …

The keen visual systems of birds have been relatively well-studied. The foundations of avian
vision rest on their cone and rod photoreceptors. Most birds use four cone photoreceptor …

Within the head capsule of the moth-fly Psychoda cinerea, underlying each of the two
compound eyes, are two internal ocelli of different sizes. There are seven photoreceptor …

For the human observer butterflies are often most attractive because of their beautiful color
patterns; the hypothesis that butterflies have color vision is therefore irresistible. Behavioral …
