I was walking a mountain while blowing bear whistle occasionally in darkness at midnight.
There was the huge tree dedicated to the gods protecting the mountain. A few dozen
meters away from the sacred tree, there was decrepit tree which was thick with mushroom.
When eyes were adapted to darkness, it revealed beautiful weak glow from Omphalotus
japonicas. It is said that Omphalotus japonicas glows for a few days after opening the
umbrella to spread spores. The decrepit tree will return to the soil by mushroom and
microorganisms. The beautiful glow was generated by the energy from last breath of
decrepit tree. The next thing I knew, it was glowing in many places of the forest. When
I turned my attention to the sky, a lot of stars were twinkling.  Bistream  K.Ohtawara

Sunny yellow light flashes to look for a partner in a forest far from town. The light flashes very strong although body length is only a few millimeters. Flashing at close to midnight must be way to live without being discovered. Male flies several dozen centimeters high from the ground but female can not fly. So that means they can not move their habitat with distance. The scene have been repeated several hundred years at same habitat. It could see many times in the past but they are absent recently. Their silent habitat is being lost by raze a forest and human being step into a forest. I am also one of human being step into habitat with camera. During last a few days, they emit luminescence without any eating by squeeze the remaining life to pass on life to the next generation. I feel drawn to such a beautiful and fugacious creature doing in a deep forest at midnight in early summer.      K.Ohtawara  Bistream

Setoden train was running in outer moat of Nagoya Castle about 40 years ago. Shigenobu Takeuchi was station staff of Setoden. Mr. Takeuchi found several tens of thousands of luminescence from Luciola parvula in the outer moat after the last train going. However, Luciola parvula were reduced drastically in next year because many people who read in the newspaper came to the moat and captured. In addition, railway was removed from the outer moat. It was large influence of environmental changes. He acted to save for their life during remaining his life against lung tuberculosis. He explained importance of the Luciola parvula to the people who come to the outer moat. The act and his fervent sprit were well known to the people. One day, public highway corporation developed a new lighting apparatus for highway of beside the outer moat which does not have leakage the light to outside from road in order to have no impact on Luciola parvula. The conservation work of Luciola parvula has continued in "The People who assume Luciola parvula in Nagoya Castle Soto-bori (outer moat)* " after he is gone. Mr. Takeuchi is the father of Luciola parvula in Nagoya Castle.
