The bees quickly learned to choose the color signaling the dish with the reward, and Menzel was able to measure how quickly the bees learned this task with various color differences. [4] Menzel's results showed that bees do not learn to discriminate between all color pairs equally well.
It is shown that red and white flowers pollinated by bees are of higher spectral purity as compared to bird-pollinated ones and are therefore easier to detect for bees. [8] Bees have trichromatic vision with maxima of peak sensitivities in UV (344 nm), blue (436 nm) and green (544 nm). [10]
The term “pollinator syndrome” describes plant characteristics that might appeal to a specific type of pollinator, including color, scent, flower shape, and more. Bees see the world around us ...
The four pigments in a bird's cone cells (in this example, estrildid finches) extend the range of color vision into the ultraviolet. [1]Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye.
Images of a Mimulus flower in visible light (left) and ultraviolet light (right) showing a dark nectar guide that is visible to bees but not to humans. Nectar guides are markings or patterns seen in flowers of some angiosperm species, that guide pollinators to their rewards.
The genus Bombus, the only one extant genus in the tribe Bombini, comprises over 250 species; [18] for an overview of the differences between bumblebees and other bees and wasps, see characteristics of common wasps and bees. The genus has been divided variously into up to 49 subgenera, a degree of complexity criticised by Williams (2008). [19]
