Colony of Bees (Horizontal) (IMAGE) Johannes Gutenberg Universitaet Mainz Caption A colony of bees on a horizontal honeycomb. The researchers rotated the honeycombs to lie horizontally, making it impossible for the bees to orientate themselves with the help of light or gravity. The hive was placed on a balance to record variations in biomass weight.
