For their sins, the gods expelled the Insect People from the first world by sending a wall of water from all directions. The Insect People flew up into the second world. Later, in the fourth world, descendents of these people were likewise punished. They escaped the floodwaters by climbing into a fast-growing reed. Cicada dug an entrance into the fifth world, where people live today. [Capinera]
