This is a very basic guide to Pollen colours ... unfortunately your computer monitors might vary a little in reproducing the colours accurately. Also the phytocidal acids that bees add to the pollen-- to stop it geminating --probably (along with enzymes) alters the true colour of the pollens that are stored in the comb ... best to watch what the bees bring in at the front door.
|The photo shows various pollen bundles, packed by the bees into the cells of their comb. The pollen, mixed with some enzymes from the bees and a bit of nectar, will ferment into “bee bread”. Later, nurse bees will convert this into nourishment for the very young bees.|
