Vulture Bees Lost and Gained Microbes

Almost all bees get their nutrients from flowers. Pollen provides protein and nectar provides carbohydrates. A group of scientists have found three closely related bees of the genus Trigona that feed off dead flesh, rather than flowers. These “vulture bees” get their protein by chewing pieces of flesh from dead animals and gain additional carbohydrates […]
