Pollen baskets by color

While out surveying the green kingdom this afternoon, I observed honey bees on the white mistflower looked different than those visiting the orangy flowers of the plateau goldeneye in our back yard. Interesting, eh? Those balls of pollen are called "pollen baskets."

You can actually identify what a bee's been foraging on by looking at the color of her pollen baskets. Here's a cool pollen chart. (They need to add a white option!)
