Bees are eaten in various forms. The brood is eaten by various peoples when it is taken from hives and crushed up with honey cambs. Xylocopa are eaten in China, and make part of a remedy for colds ... so-called Chinese plums are another part of the recipe. I have seen "baby-bees" in chocolate sold as a gourmet item. In Japan, bee brood is, or has been, used for feeding Coocinelidae for rearing to biocontrol purposes. Cheers, Peter
