Beesand Colour

On our table in the garden we put a blue card,and all around this blue card we put a number of different grey cards. Thesetrey cards are of all possible shades of grey and include white and black. Oneach card a watch-glass is placed. The watch-glass on the blue card has somesyrup in it; all the others are empty. After a short time bees find the syrup,and they come for it again and again. Then, after some hours, we take away thewatch-glass of syrup which was on the blue card and put an empty one in itsplace.

Now what do the bees do? They still go straightto the blue card, although there is no syrup there. They do not go to any ofthe grey cards, in spite of the fact that one of the grey cards is of exactlythe same brightness as the blue card. Thus the bees do not mistake any shade ofgrey for blue. In this way we have proved that they do really see blue as acolour.

We can find out in just the same way what othercolours bees can see. It turns out that bees can see various colours, but theseinsects differ from us as regards their colour-sense in two very interestingways. Suppose we train bees to come to a red card, and, having done so, we putthe red card on the table in the garden among the set of different grey cards.This time we find that the bees mistake red for dark grey or black. They cannotdistinguish between them. This means that red is not a colour at all for bees;for them it is just dark grey or black.

That is one strange fact; here is another. Arainbow is red on one edge, violet on the other. Outside the violet of therainbow there is another colour which we cannot see at all. This colour beyondthe violet, invisible to us, is called the ultra-violet. Although it isinvisible, we know that the ultra-violet is there because it affects aphotographic plate. Now, although we are unable to see ultra-violet light, beescan do so; for them ultra-violet is a colour. Thus bees see a colour which wecannot even imagine. This has been found out by training bees to come for syrupto various parts of a spectrum, or artificial rainbow, thrown by a prism on atable in a dark room. In such an experiment the insects can be taught to fly tothe ultra-violet, which for us is just darkness.
