the elephant hawk moth Deilephila elpenor, nocturnal colour vision is now known from two …

Humans lose colour vision at night and it has often been assumed that this happens to other
animals as well. It is not true of nocturnal moths, however: a recent study has shown that the …

Honeybees, like humans and most other vertebrates, are colour-blind in dim light. Bees are
primarily day-active and have apposition compound eyes, the typical eye design of diurnal …

Recent studies have shown that certain nocturnal insect and vertebrate species have true
color vision under nocturnal illumination. Thus, their vision is potentially affected by changes …

Diurnal and nocturnal hawkmoths (Sphingidae, Lepidoptera) have three spectral types of
receptor sensitive to ultraviolet, blue and green light. As avid flower visitors and pollinators …

Colour vision allows animals to use the information contained in the spectrum of light to
control important behavioural decisions such as selection of habitats, food or mates. Among …

Studies on animal colour vision typically focus on the chromatic aspect of colour, which is
related to the spectral distribution, and disregard the achromatic aspect, which is related to …

Humans are colour-blind at night, and it has been assumed that this is true of all animals.
But colour vision is as useful for discriminating objects at night as it is during the day. Here …

The dual retina of humans and most vertebrates consists of multiple types of cone for colour
vision in bright light and one single type of rod, leaving these animals colour-blind at night …
