Hives of bees and wasps support heavy weights using hexagonal cells in offset positions.
"The hexagonal cells of bees and wasps create an extraordinarily strong space-frame, in particular in the vertical bee comb with two cell layers back to back with half a cell's shift in the position to create a three-dimensional pyramidal structure. The extraordinary strength is exemplified by a comb 37 centimetres by 22.5 centimetres in size, which is made of 40 grams of wax but can contain about 1.8 kilograms of honey." (Pallasmaa 1995:81,101)
"A bees' honeycomb is one of the wonders of the world. Layer upon layer of hexagonal cells of identical size and shape are stacked together as precisely as if the bees had worked to a grid drawn on graph paper. But why should bees build hexagonal cells? Why should they not be square, like boxes, or circular?…As we have already noted, natural organization is economical, expending the least amount of energy and using the least material necessary for a task…Three-way junctions of 120° angles occur quite widely in nature, being the most economical angle for joining things together." (Foy and Oxford Scientific Films 1982:30)
