It's hormiga culona season!
Those are ants collected in Santander Province, near the Venezuelan border, which are sold in little plastic bags costing a few thousand pesos. They were a traditional food of the Guanes indigenous people, providing proteins for their diet, and are now a popular novelty food. They taste crunchy and salty, and even have their own web site.
The ants are also a bit risque. Hormigas culonas means 'big-butt ants.' And some say they're aphrosidiacs. Go find out for yourself.
