Why do bees create such precise structures and the wasps such messy ones? Scarcity. The wasps build with material that is abundant: mud. The bees build with material that is scarce: wax. The bees’ wax—like space in a tight suitcase or dollars during hard times—must be conserved. Building badly means wasting wax, which is an incentive to be efficient, to pack well. The wasps, on the other hand, have abundant material, plenty of mud to waste. Wasps can afford slack—to build sloppily—because their building material is cheap. The bees cannot because theirs is expensive.
