On Saturday, March 16, we released firefly larvae into Hatsukawa within Atami Plum Garden.
As an annual tradition, children from Umeenomachi helped us again!
Japan is said to be home to around 50 species of fireflies.
The species released in Atami is Japan’s representative firefly, the genji-botaru. We hatch the larvae, feed them kawanina (freshwater snails) about once a month while raising them, and release the final-instar larvae when they reach 2–3 centimeters.
These larvae leave the river on humid nights from mid to late April, burrow into the soil, and form oval “soil cocoons.”
Inside those soil cocoons they pupate and emerge as adults from late May to early June.
This year we will hold “Evenings for Firefly Viewing” from Saturday, June 1 through Sunday, June 9.
Please come and see the pale glow of the fireflies that can be seen only during this season.
