How geometry solves architectural problems for bees and wasps

What were once thought of as nest flaws are the solution to combining hexagons of different sizes

The nests of honeybees (one shown) consist of mostly hexagonal cells made from wax, but pairs of five-and seven-sided cells help fit together hexagons of different sizes.

Honeybees and yellow jackets don’t look much like mathematicians — for one thing, they’re smaller. But collectively, the insects can solve a common architectural conundrum using a geometric solution that they evolved independently of each other.
