Why firefly glow at night |
| Answer» Fireflies, also known as lightning bugs, glow to lure prey, discourage predators, and most importantly to attract mates. The characteristic green-yellow glow produced by a firefly is the result of a chemical reaction that takes place in the insect\'s abdomen. This chemical reaction involves three ingredients: luciferin , luciferase , and oxygen . This light is sometimes called “cold light” because it generates so little heat. | |
