We were at a shelter in 2010 and of course we were all sitting around a campfire. Next thing you know there were bugs everywhere. It looked like maybe they were crawling out of a burning log, they do that sometimes. Well they weren't. They where everywhere. My tent was 50 yards away they where there too. In one square foot there were at least 30 - In Each and every square foot. In all directions. They looked similar to centipedes but more like millipedes, but didn't really look like baby millipedes. I've seen a swarm of Locust's while driving in a car that was so thick it gave you that dizzying feeling like driving in the snow. I've also seen Salmon run - upstream - in Oregon, kinda of a swarm thing. Of course bees.
So I know some insect, swarm.
Has anybody seen any swarms like that in nature? What was it? What did you see? what did I see?
