The colour loci in the colour hexagon of honeybees, calculated for white spiders (grey squares, N=50), white daisies (black triangles, N=55), yellow spiders (white circles, N=30) and yellow daisies (black asterisks, N=55). The distribution of the colour loci of white flowers ends at the point indicated by the arrow. B, blue; G, green; U, UV.
