Seems it's Bioluminescence week!

I'm actually just seeing this your detailed post about this awesome phenomenon! I wrote something about it today - more about it being a potential energy source though.

This cracked me

The primary reason fireflies glow is mating. Just like boys tend to spray lots of colognes in an attempt to lure girls, the male fireflies of a certain species tend to glow in other to attract female counterparts of the same species

and then the killer

In clearer words, female fireflies sometimes glow, attract males and eat them. Such a sad story.

So sad and pitiable...In simple words, not all that glitters is gold!

Well done
