A study of managed bumble bees and honey bees on a blueberry farm finds that most of the pollen they collect comes from other plants, suggesting that supplementing crops with a diversity of nearby plant types makes for healthier bees. After collecting pollen from bees returning to hives, researchers analyzed pollen types under a microscope, finding a wide variety, from plants such as blueberry, buckthorn, cherry, and many more.
