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 …

The visual displays of animals and plants are often colourful, and colour vision allows
animals to respond to these signals as they forage for food, choose mates and so-forth. This …

Background Color vision is commonly assumed to rely on photoreceptors tuned to narrow
spectral ranges. In the ommatidium of Drosophila, the four types of so-called inner …
