You are a habitat. An ecosystem A microbiome. The most popularised microbiome, and commercialised, is your "friendly" gut bacteria. Probiotic drinks and yogurts are a common product in supermarkets, but humans are not unique in supporting a microbiome. Every living organism has its microbiomes and honey bees are no different. In fact, recent research has shown that colonies positioned near areas of low biodiversity (think improved grassland for pasture or conifer plantations) have decreased bacterial diversity in their diet. So like humans, healthy bees need diversity in their diet. Variety really is the spice of life.
