The firefly is a holometabolic insect, passing through the stages of being an egg, being a larva, molting, and pupation. 萤火虫属于「完全变态」的昆虫,一生历经卵、幼虫、蜕皮、化蛹及羽化的过程。
The Lampyridae are a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers.
