Lampyridae is a family in the beetle order Coleoptera. They are commonly called fireflies, lightning bugs due to their conspicuous nocturnal or more accurately crepuscular use of bioluminescence
to attract mates or prey. Fireflies are capable of producing a "cold light" containing no ultraviolet or infrared rays, with a wavelength from 510 to 670 nanometers, pale reddish, yellowish or green in colour.
There are more than 2,000 species of firefly found in temperate and tropical environments around the world. Many species can be found in marshes or in wet, wooded areas where their larvae have abundant sources of food. These can also emit light and are often called "glowworms", particularly in Eurasia. In the Americas, "glow worm" also refers to the related Phengodidae.Firefly - Wikipedia, the free encyclopedia
