This is the craziest thing ever. I woke up this morning and found this on my porch up at the mountain house. At first I thought it was dog poop and silently cursed the dog who dared leave his calling card on my porch. But then I noticed it was moving so I went outside to get a closer look and realized that it was dozens of centipedes! They reminded me of beached whales and I wondered what in the world they were doing all piled up on top of each other, sometimes holding perfectly still and other times waving their legs around as if in a frenzy. Apparently they do this during the rainy season. They all pile up and they move as one body. When they want to move from one place to another they ALL go, sort of like leap frog. The ones in the back walk over the ones in the front and move to the front of the pile. Then the ones who are left in the back do the same thing. This is how they move around and they never separate from the pile.
There was another mound of centipedes very near to the first mound that was on my porch. By noon, these guys had dispersed but the ones on the porch had moved forward about three yards. It took them over four hours to cover that distance as a group, whereas if they’d just walked individually it would only have taken them a few seconds. Amazing.
