TABLE XXXIV 

 Colour Contrasts of Honey Guides 



From this it appears that, in fact, the honey guides are 

 always such that the eye of the bee can distinguish them 

 from the ground colour of the corolla. The frequency of 

 the yellow-blue contrast is very striking, and, along with 

 white-blue and white-yellow, makes up the great majority of 

 combinations as seen by the bee's eye. 



Further interesting experimental results were obtained. 

 It was found that bees could distinguish between, for 

 example, a yellow circle surrounded by a blue ring, and a 

 blue circle surrounded by a yellow ring. The former is 

 the design of a forget-me-not flower. It can distinguish 

 between different designs in a single colour. Thus a
