Machismo expresses itself in many ways south of the border it seems, including in young boys in Oaxaca(Mexico) thinking nothing of going Scorpion Hunting and reselling the charming creatures to local Mezcal distillers who add one of these friends in some of their local production. One of the best known Mezcal producers is Del Maguey. 
Mezcal is made from the maguey plant which comes in many types. Maguey worms (caterpillars) are also one of the insects treated as a delicacy by locals.
What piqued my interest in the topic was Would you like a scorpion with that, sir? by Tom Sutherland in the FT Week-end.
