Swallowtail butterflies are large butterflies that live in Japan and sleep on grass stalks at night. "Himebotaru" is a small firefly that lives in the forest and has a body length of about 6 to 8 mm. They give off a powerful light for a short time like a flash. I have been investigating and taking pictures of this firefly habitat for 10 years. "Himebotaru" lives near people, but because it is not well known, its habitat may be destroyed by roads. I want people to know the existence of this firefly first, so I continue to shoot.
