Abstract

Honeybees construct nests that consist of tessellated hexagonal prismatic structures. The bees develop a linear succession of tetrapod structures that serve as the nest’s foundation in the initial stage of construction. This natural hexagonal lattice structure has been the epitome of extensive aeros...
