Light of my life, fire of my loins. My sin, my soul.


{ There are about 2,000 species of fireflies, a type of beetle that lights up its abdomen with a chemical reaction to attract a mate. That glow can be yellow, green or pale-red. In some places the firefly dance is synchronized, with the insects flashing in unison or in waves. The lightshow has also been beneficial to science—researchers have found that the chemical responsible for it, luciferase, is a useful marker in a variety of applications, including genetic engineering and forensics. | Smithsonian magazine | full article }
