June 10th- June 15th, 2024 is Summer – BOSHU (Grain beards and seeds)-26th KOU “Rotten grass becomes fireflies.”
It’s time for fireflies (HOTARU) to fly around. HOTARU has another name “Rotten grass.” But why does rotten grass turn into fireflies.
Firefly larvae that emerge from the water on land grow into adults in holes dug in the soil. They then crawl out of the holes and wander around the nearby grass.
The Edo people who saw the fireflies crawling out may have believed that “rotten grass turns into fireflies.” In a sense, the Edo people were good at observing nature.
In mid-April, there is an elementary school where firefly larvae are released into the stream that runs through the schoolyard. So yesterday (June 11th), I went to check on them.
I was lucky to find “one” firefly that was glowing. According to a man who came to see the fireflies like me, “fireflies often come out after it rains.”
Yesterday in Nagano City, the maximum temperature was 30°C and the humidity was 31%. Today’s forecast is over 30°C, and we will have to wait until the 16th for the rain to come.
Around here, rice planting is almost over. Both the rice field and the rotten grass are looking forward to the rain.
