Q: What do honeybees eat?
A: A queen eats only royal jelly (a glandular secretion of a worker bee). Worker bees eat royal jelly until they are 3 days old. After that, their diet changes to pollen, honey, nectar, and water. Drones have a diet similar to that of worker bees, although in different proportions.
