In my last post, I broke down the science of why some caterpillars work together and form these strange, writhing formations known as rolling swarms. In a sentence: the caterpillars use their own bodies as a constantly re-assembling and dis-assembling conveyor belt, and by doing this they manage to give themselves a speed boost.

Inspired by this notion of co-operating caterpillars, my friend Deepak decided to dig a little deeper, and try to understand why they work together in the first place.
What if, he asked, each caterpillar was just behaving selfishly, and only trying to overtake the caterpillar ahead of it? With that simple rule, would such harmonious, collective behavior emerge?
