When the Spanish arrived, they were initially horrified by entomophagy (insect-eating). However, hunger and curiosity eventually overcame disgust. Colonial chronicles note that Spanish settlers quickly came to appreciate the “little toasted grains” that the natives offered. Over centuries, the hormiga culona transcended the indigenous sphere to become a regional symbol of santandereanidad —the identity of the people of Santander.

The very popularity that has revived this tradition now threatens it. As demand has grown—from urban Colombians and international chefs—the pressure on wild ant colonies has intensified. In some areas around San Gil and Barichara, harvesters report that it is harder each year to find the queens. The forest is being fragmented by cattle ranching and eucalyptus plantations (which are toxic to the ants’ native fungi). Moreover, a practice known as sobrecosecha (overharvesting) occurs when harvesters take too many queens from a single colony. If too many queens are removed in a single season, the colony’s ability to reproduce collapses.

If you find yourself in the departments of Santander or Boyacá between late March and June, do not miss the chance. Here is how to approach your first hormiga culona :

The harvesters do not swat or chase. Instead, they gently gather . Using soft brooms or even their hands, they sweep the teeming queens into buckets, sacks, or calabash bowls. The sound is distinctive: a soft, persistent pattering like rain on leaves, as hundreds of queens drop from the low vegetation or stumble across the tarps. A good morning’s harvest might yield five, ten, even twenty kilograms of live, squirming queens.
