In 1928 Japanese scholars announced that a type of water-bred insect which could be found all across that country was a unique species. Since then people have discovered that in fact there are many varieties of water-bred fireflies. Already three types are known in Taiwan, one of which is the "yellow-green firefly" which is common in the plains.
