Fireflies produce cold light, meaning there is no heat produced as a by-product. Fireflies generate light by mixing a chemical (luciferin) with an enzyme (luciferase) and oxygen. Fireflies produce their light by controlling the oxygen supply to the light organs that contain the chemical reaction. Fireflies use their light to attract each other, which is rare, as most insects use scent instead of sight.
As I again, feel like these little cuties are known the world round, I will launch into some fun stuff, like some Japanese folklore as to where they came from:
Once upon a time, a woodman and his wife lived on the edge of a beautiful forest beneath Mount Fujiyama in Japan. They had a cozy, little house and a beautiful garden, however they were not happy, because they wished for a child. One moonlit night, the wife slipped out of the house and laid herself down before the great mountain with its shining snowcap. She begged for Fujiyama to send her and her husband a child.
As she prayed, a tiny light appeared high upon the mountain and began to drift down toward the woman. When the light reached the branches of the bamboo, it stopped. The woman was overjoyed when she found it was a Moonchild, sent by the Lady in the Moon herself. She took the child home and her husband was overjoyed as well.
The Moonchild grew into a beautiful young lady, a Moon Princess, and was beloved by all who saw her. When the Emperor’s son saw her, he asked for her hand in marriage. However, she refused, saying that her mother, the Moon Lady, had bidden her to return home when she reached the age of twenty.
When the night came for her to leave, the woodman, his wife and the Emperor’s son were all there to say goodbye, and they were inconsolable. The Lady in the Moon sent down a silver moonbeam for her daughter, and the Princess floated up upon it. As she floated, the Princess cried silver tears for those she left behind. As they fell, they took wing and flew all over the land.
The Moon Princess’ tears can still be seen on moonlit nights. Some call them fireflies, but those who know the legend know that they are the Princess’ tears, searching for those she loved on Earth and had to leave behind.
This is a great video segment about the Fireflies in Tennessee, they are very unique.
