I was photographing honeybees working an early pollen source last spring - Allium Allium christophii 'Star of Persia' (Photo 1).
I noticed that the pollen carried by the honeybee was an interesting grey color. This led me to wonder about pollen colors. I did some research and came up with a dizzying array of pollen colors represented in Table 1).
Photo 2 shows a bumblebee with the off white pollen of Sedum.
As spring approaches keep an eye out for the array of pollen colors offered by our spring flowers (Photo 3) and carried by our insect pollinators (Photo 4).
