Researchers at Tufts University have discovered that honey bees alter their diet of nutrients according to the season, particularly as winter approaches. A spike in calcium consumption in the fall, and high intake of potassium, help prepare the bees for colder months when they likely need those minerals to generate warmth through rapid muscle contractions. A careful inventory of the bees’ nutrient intake revealed shifting sources (from flowers to mineral rich ‘dirty water’) and how limitations in nutrient availability from these sources can have implications for the health of both managed and wild colonies.
