Reuters — Bees at a cluster of apiaries in northeastern France have been producing honey in mysterious shades of blue and green, alarming their keepers who now believe residue from containers of M&M’s candy processed at a nearby biogas plant is the cause.
Honey bees represent only a small fraction of the roughly known species of bees. Some other types of related bees produce and store honey, but only members of the genus Apis are true honey bees. The study of honey bees is known as melittology.
Honeybees on comb filled with nectar. The nectar gathered from flowers is watery so once bees fill up the combs they then fan their wings to evaporate the excess water. The honey gets thick and the bees know when it's cured so that they can cap it.
