萤火虫是亮尾巴的小甲虫。盛夏的夜晚,繁星满天,萤火虫就会举着“小灯笼”在田边河畔,草地庭院,闪烁不定地上下飘动,煞是一幅美好的景象。萤火虫的光是从哪里发出来的?它为什么会发光呢?这一直是我想了解的问题。我查找了许多资料,原来萤火虫的光是由身体中特殊的发光器发出来 Fireflies are bright tail small beetles. Summer night, starry sky, the firefly will hold a “small lantern” in the Tanabe riverside, grass courtyard, flashing up and down waving, it is truly a beautiful scene. Where does firefly light come from? And why does it glow? This has always been a problem I want to know. I found a lot of information, the original firefly light is issued by the body’s special light emitters
