GeoVideo 0020 Army Ant Death Spiral 1080p

Ants secrete a pheromone called Trail pheromones so it can lead members of its own species toward a food source. Like a cube of Borg drones that's been separated from the collective, these army ants were somehow separated from the main foraging party and they lost the pheromone trail and began to follow one another, forming a continuously rotating circle. The ants that are stuck in the "antnado" will usually die of exhaustion. Luckily for these ants, they only swirled for about half hour and then another half hour later, not an ant could be seen. It's a real-life Antnado! (yes, I'm claiming to be the first one to coin the name).
