Unraveling the mystery of massive, multi-legged swarm stopping trains



For more than a century, thousands of venomous centipedes have swarmed on train tracks in Japan’s dense forested mountains, forcing trains to stop. These “train millipedes”, so-called because of their known obstacles, would appear to anyone so often – and then disappear again for years. Now scientists have understood why.

It turns out that these millipedes (Parafontaria laminata armigera), endemic to Japan, have an unusually long and synchronous eight-year life cycle. Such long “periodic” life cycles – in which a population of animals moves simultaneously during the life stages – have only been confirmed earlier in some species. cicadas with a 1

3- and 17-year life cycle, as well as bamboo and some other plants.
