What does a honey bee eat? Pollen, nectar, fungus spores, cow food, flour, brood, fruit, rubbish, anal secretions of insects, and a lot of other weird things!
This is a superfood. For bees, a diet consisting of royal jelly for the entire larval stage will cause a female egg to grow into a big, reproductively capable queen bee.
Pollen is collected from flowers by bees. It is a rich and variable source of proteins, lipids, vitamins, and minerals. On average it apparently contains about 22-23% protein.
Bees eat pollen, nectar, and honey. They also will eat sugar solutions that they extract from fruit and insects, and they can get creative in terms of eating powders that have protein in them.
