We have been able to see fireflies along the brook every year since we started cleaning it and we think our effort with firefly protection project is highly evaluated. 

On April 20th, we just walked along the brook to check the freshly built "Firefly" signboards. It was still a little chilly at night, but we could observe firefly larvae coming on shore in closeup.  It was so beautiful to see the faint lights coming from the firefly larvae that it made me forget about the cold rain.

We could observe about 20 lights of firefly larvae while walking along the brook. They will start flying as beautiful fireflies after approximately 40-day pupa stage. 

"Ono Association for Firefly Town" is written on the back of the signboard.	Firefly larva with shining bottom
Firefly larva moves slowly, at the speed of a few centimeters per minutes.	It is just a small stone, but a huge obstacle for a tiny larva.
It is almost at the place where it can make cocoon. Keep on moving!!!
