How cool is that?? The nice thing is that I would pass by them all day without even knowing they glow during the night!
I did a quick research and it looks like they were kinda unknown in Brazil, it wasn't until the 2000' that some guys have started researching them, they found a especies called Gerronema viridilucens

As I've read there are 71 especies in the World, 12 in Brazil... and I haven't seen any single one! Guess I'll have to do some nigh exploration hahahahha
Love, love you article. You brought something cool that I didn't know about.
