Genjibotaru

"Genjibotaru" is the most common firefly and is said to be a summer feature in Japan. It is a large firefly with a body length of about 20 mm, and it lives in rivers when it is a larva, and remains around rivers even as an adult. "Genjibotaru" flies while glowing for several seconds, so when you take a photo, it appears as a green line.

「源氏ボタル」は日本の夏の風物詩と言われる最も一般的な蛍です。体長が約20ｍｍある大型の蛍で、幼虫の時期には川に居るので、成虫になっても川の周辺に居ます。源氏ボタルは数秒間光りながら飛ぶので、写真に撮ると緑色の線として写ります。
