Japanese version is here .
Once upon a time when Nintendo game was not invented yet, children used to play around on grasslands. The targets of their hunting instinct were dragonfies, such as Anax parthenope and Anotogaster sieboldi. The scenes imprinted in my deep mind while I was an infant, were a fresh, just emerged imago of Anotogaster sieboldi, and a few adult Sympetrum pedemontanum, whose wings were cut half, floating on a clear water by a paddy field. I started again the life with dragonflies since I got a postgraduate student, because I was interested in its simple way of life and their great diversity in Japanese archipelago. Dragonfies have been part of my life till now.
