We don't mean the man-made beehives for domesticated honeybees in apiaries, though they are cleverly designed and serve their purpose well; we mean the natural beehives found in nature and originally created by the bees themselves.
Bees usually look for hollowed-out locations to create a nest, such as a hollow tree, caves or rock cavities, where they then create the typical, instantly recognizable, hexagonal honeycomb arrangement. The arrangement of beehives is fairly regular, with honey stored at the top, followed by pollen storage, and finally worker and drone-breeding cells at the bottom. There can be found the slightly protruding, vaguely peanut-shaped cell for the queen bee at the very bottom.
What you may not know: Honeycombs are the ideal shape to economize labor and material yet create a structurally sound and strong structure, and are used in many man-made applications.
