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 …

We discovered nocturnal colour vision in the Asian giant honeybee Apis dorsata—a
facultatively nocturnal species—at mesopic light intensities, down to half-moon light levels …

Background: Some bees and wasps have evolved nocturnal behavior, presumably to exploit
night-flowering plants or avoid predators. Like their day-active relatives, they have …

The ability to see colour at night is known only from a handful of animals. First discovered in
the elephant hawk moth Deilephila elpenor, nocturnal colour vision is now known from two …

In response to the pressures of predation, parasitism and competition for limited resources,
several groups of (mainly) tropical bees and wasps have independently evolved a nocturnal …

Colour vision was first demonstrated with behavioural experiments in honeybees 100 years
ago. Since that time a wealth of quality physiological data has shown a highly conserved set …

Most bees are diurnal, with behaviour that is largely visually mediated, but several groups
have made evolutionary shifts to nocturnality, despite having apposition compound eyes …

The optical design of most insect apposition compound eyes should restrict activity to
daylight because at night the tiny lenses of the isolated ommatidia cannot collect sufficient …

Colors are meaningful signals for honey bees. The information value originates from the
phylogenetic experience of the species and the ontogenetic experience of each individual …

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 …
