Feu follet (fifolet)
Cajun and Creole Louisiana call the will-o'-the-wisp of the swamps the feu follet or fifolet, a wandering light said to be a soul doing penance, or to guard Lafitte's treasure.
1895 CE · 29.80, -91.50 · status: legend
The account
Alcée Fortier and other 1890s collectors noted it in Louisiana French folklore. Tradition says a needle stuck in a tree will trap it.
The sceptical view
Will-o'-the-wisps are usually linked to burning marsh gases, though they are hard to observe.
