Reconstruction
Roasted içás or tanajuras are the reproductive females of leafcutter ants in the genus Atta. Unlike worker ants, these queens leave established nests on seasonal nuptial flights, usually associated with warm, wet weather. Their sudden appearance creates a short harvest window: collectors gather them from the ground or intercept them near colonies, then remove the wings and often the legs or other hard parts. The comparatively large abdomen contains reserves intended to sustain a queen while she founds a new colony, making it notably rich in fat as well as protein.
Indigenous communities in Brazil ate these ants before Europeans established colonies there. The practice entered the surviving written record in 1587, when Portuguese planter and chronicler Gabriel Soares de Sousa described large ants in Bahia being toasted and eaten. His account is evidence for consumption at that time, not an origin date. Nor does it establish every detail of the modern recipe. Indigenous knowledge, transmitted outside European writing, necessarily predates the colonial observation, although its antiquity cannot be assigned a precise year from the available evidence.
The simplest preparation is to toast or fry the cleaned queens until browned, aromatic and crisp. They may then be seasoned and eaten as a snack. A well-known Brazilian preparation combines them with farinha de mandioca: toasted cassava flour is stirred with the ants, salt and sometimes added fat to produce farofa. Recipes differ substantially. Some emphasize whole insects, while others crush the ants or use their abdomens to flavor a larger quantity of flour. Cassava, itself an Indigenous South American domesticate, provides a dry, starchy base that extends the seasonal harvest.
Names and practices vary by region. Içá commonly refers to a queen of the saúva leafcutter ants, while tanajura is another widespread regional term. The food is particularly associated with parts of southeastern and northeastern Brazil, but the terminology, species collected and methods are not uniform. Comparable harvesting of large Atta queens also occurs elsewhere in South America; similarity alone does not prove that all such traditions descend from one historical practice.
Today, roasted queens and ant farofa survive as seasonal foods, local delicacies and expressions of regional identity. Their persistence demonstrates how close observation of insect life cycles can turn a brief ecological event into food. It also challenges the colonial tendency to portray Indigenous entomophagy as exotic rather than technically informed. Modern availability can be affected by pesticide use, urbanization and habitat disturbance, while informal collection and household recipes make both supply and nutritional composition highly variable.

Historical context
Bahia was a major center of Portuguese colonization on the Atlantic coast. Salvador, founded in 1549, served as colonial Brazil’s capital, while coastal sugar estates expanded through Indigenous dispossession and the forced labor of Indigenous and increasingly African people. Cassava remained a fundamental food across social groups because it grew well in tropical soils and could be processed into durable flour. European descriptions preserved fragments of Indigenous food knowledge, but they filtered that knowledge through colonial interests and rarely recorded how long particular practices had existed.
Evidence
Written sources
StrongA 1587 Portuguese description from Bahia directly attests that large ants were toasted and eaten, although it records an existing practice rather than its beginning.
Food identification
ModerateThe vernacular terms içá and tanajura consistently refer to winged reproductive females of leafcutter ants, especially Atta, but naming and species identification vary regionally.
Preparation method
ModerateToasting is supported by the early written description and remains documented in living practice. Frying and combining the ants with seasoned cassava flour represent variable later or continuing regional preparations.
Recipe evidence
LimitedThere is no single standardized historical recipe. Ingredient proportions, removal of body parts, use of added fat and the balance between insects and cassava flour vary among households and regions.
Dating
StrongThe year 1587 is defensible as a date of surviving written attestation, but not as the date when the Indigenous practice originated.
Geographic attribution
ModerateThe early account supports consumption in colonial Bahia, while later practice is associated with several northeastern and southeastern Brazilian regions rather than one exclusive origin point.
Historical interpretation
ProbableInterpreting the harvest as ecological expertise is supported by the predictable seasonal flight of ant queens and by continued collection practices, but the details of sixteenth-century harvesting were not fully recorded.
Limitations
- moderaterecipe
The early account supports eating toasted ants but does not establish the complete modern formula of cassava flour, added fat and salt. That formulation should be understood as a reasonable representation of later regional farofa rather than a verbatim 1587 recipe.
- minordate
The year 1587 marks a surviving colonial written description, not the origin of the dish. Indigenous consumption was already established and is older, but cannot be assigned a precise beginning.
- minoringredients
Içá and tanajura are regional names rather than precise species labels. The harvested insects are generally Atta queens, but the particular species can differ by locality.
