![]() ![]() Vegetation develops depending on the climate, the soil pH, moisture levels, soil drainage, and winter maximum and minimum temperatures. In fact, you can notice the color differences both on the pollen baskets of honey bees and in the bee bread inside the hive. Pollen can range from blue to yellow to red to green and everything in-between. Take a moment to look at the pollen-laden plants in your neighborhood and you will see they contain a wide variety of pollen colors. Colorīees prefer purple, blue, yellow, and white flowers Through my research, I found out there are many different ways honey bees decide which flowers to visit, including color, taste, patterns, popularity, and even electrical fields. They bring pollen back to the hive to be repurposed into bee bread for developing larvae. ![]() Though bees gather the pollen on their legs or even on the hairs on their abdomen (I’m looking at you, mason bees ), the adult bees don’t consume it. When I learned this, I started to wonder how bees decide what flowers to visit and if they have taste preferences when it comes to pollen. In fact, flowers evolved alongside bees to be more colorful and to be richer sources of pollen. We aren’t 100% sure how the evolution happened, but at some point, a wasp had a run-in with some pollen, began to consume it, and *poof* now we have honey bees who have a mutually beneficial relationship with flowers. *Gasp* I know, I was a bit conflicted as well when I learned that fun fact.
