Answer 2

The Lampyridae are a family of insects in the beetle order Coleoptera. They are winged soft-bodied beetles, 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.[2] Some species such as the dimly glowing "blue ghost" of the Eastern US are commonly thought to emit blue light (<490 nanometers), however this is a false perception of their truly green emission light due to the Purkinje effect.[3]
