Mexico — Chapulines and the Deep Pre-Columbian Tradition

What it is

Mexico is home to one of the world's richest, most documented, and most culinarily sophisticated insect-eating traditions. Far from being a survival practice or a rural remnant, Mexican entomophagy is a living culinary culture centered in Oaxaca and extending through much of southern and central Mexico, with active markets, seasonal celebrations, specific culinary preparations, and a pre-Columbian history traceable to Aztec codices.

History & domestication

Insect consumption in Mesoamerica predates written records. The Aztec civilization had a well-documented insect-eating culture: the Florentine Codex (the great 16th-century encyclopedia compiled by Franciscan friar Bernardino de Sahagún from indigenous informants) records dozens of edible insects by their Nahuatl names, including detailed descriptions of how they were harvested and prepared. The Aztec marketplace at Tlatelolco, described by Spanish conquistadors, sold insects alongside maize, beans, and game. Bernal Díaz del Castillo's Historia verdadera de la conquista de la Nueva España records insect vendors at Aztec markets, though the Spanish reaction ranged from curiosity to disgust.

The continuity of Mexican insect-eating through colonization, through the imposition of Spanish foodways, and into the modern era is itself a remarkable piece of cultural history. While many Aztec food practices were suppressed or transformed under colonial rule, the insect-eating tradition persisted — partly because it was too deeply embedded in rural subsistence culture to easily eradicate, partly because insects were not easily incorporated into the Spanish dietary taxonomy that placed animal foods into a hierarchical value system favoring domesticated livestock.

Today, approximately 549 species of insects are consumed in Mexico, the highest documented count of any single country in the world. This abundance reflects both the extraordinary biodiversity of Mexican ecosystems and the long cultural attention paid to wild insect species as food.

Chapulines — The Flagship Insect: Chapulines (singular: chapulín) are toasted grasshoppers, the most famous and widely consumed insect food in Mexico and one of the most widely recognized globally. The primary species consumed is Sphenarium purpurascens, the Mexican grasshopper, though several related species are also consumed in different regions and seasons. The word chapulín derives from the Nahuatl chapolin, meaning grasshopper or cricket.

The traditional preparation of chapulines is specific and ancient: the grasshoppers are first briefly blanched or boiled to kill them and remove any pathogens, then toasted dry on a comal (the traditional flat griddle used throughout Mexican and Central American cooking) until crisp. During or after toasting, they are seasoned with lime juice, salt, and chili powder — typically chile de árbol or other dried red chile varieties. The result is a crispy, intensely flavored snack that is simultaneously sour, salty, savory, and mildly spicy. The flavor is often described by Mexican food writers as having an umami backbone with grassy, nutty notes.

Chapulines are integral to Oaxacan cuisine specifically. The Benito Juárez market in Oaxaca City — one of the great food markets of Mexico — sells chapulines in enormous quantities from dedicated vendors who offer them in different sizes (small, medium, large), different spice levels, and in different packaging for tourists and locals alike. They are consumed as a snack, used as a taco filling, integrated into tlayudas (Oaxacan flatbreads), sprinkled over guacamole, and incorporated into mole sauces and memelas.

The seasonal dimension of chapulin consumption is important. Wild chapulines are harvested between approximately May and October, coinciding with the rainy season when grasshopper populations are largest. The harvest is a community activity in many Oaxacan communities, with groups gathering early in the morning to collect grasshoppers by hand or with nets before the insects become active in the heat of the day. Increasingly, chapulines are also farmed in controlled conditions to meet year-round urban demand.

Nutritionally, chapulines are exceptionally dense: approximately 60–75% protein by dry weight, with good amino acid profiles, significant iron content, and high levels of omega-3 fatty acids. They are also notably low in fat compared to many other edible insects. This nutritional profile, combined with their established culinary status, has made chapulines the insect most commonly introduced to Western food contexts by Mexican-American chefs and food journalists.

Escamoles — The Caviar of Mexico: Escamoles (singular: escamol) are the eggs and larvae of the giant black Liometopum ant (Liometopum apiculatum), harvested from the root systems of maguey (Agave spp.) and other desert plants in the central Mexican states of Hidalgo, Tlaxcala, and Puebla. They are among the most expensive ingredients in Mexican cuisine — frequently priced at several hundred pesos per kilogram at market, and correspondingly priced at upscale Mexico City restaurants — and have been consumed since pre-Columbian times as a delicacy associated with royal and elite Aztec feasting.

The "caviar of Mexico" epithet is apt in culinary terms: escamoles are small, pearl-like, ivory-white, and have a delicate, buttery flavor with a soft, slightly creamy texture that is unlike anything else in the insect food world. They do not taste insecty in the way that many Western consumers fear — the flavor is mild, rich, and faintly nutty, sometimes compared to cottage cheese or hominy.

Harvest is labor-intensive and dangerous. Liometopum ants are aggressive defenders of their colonies, and harvesters must dig carefully into the root systems of maguey plants in late February through April (the brief seasonal window when the larvae are present) while managing ant bites. The colonies are harvested sustainably — experienced harvesters remove only part of the brood and disturb the colony as little as possible to allow it to regenerate the following year. This traditional sustainable harvest model has deep roots in the communities that practice it.

The traditional preparation of escamoles is simple: they are sautéed in butter with epazote (Mexican herb), onion, and serrano chile, then served as a taco filling or as a side dish with fresh tortillas. The butter complements their natural richness. In upscale contexts, escamoles appear in more complex preparations — with cured salmon, in emulsified sauces, in composed salads — but traditional preparations remain the benchmark.

The Maguey Worm — Chinicuil: The maguey worm or chinicuil (chinicuiles in plural) is the larva of the Comadia redtenbacheri moth (red maguey worm) or the caterpillar of the Aegiale hesperiaris butterfly (white maguey worm), both of which live inside the stems and root systems of maguey (Agave) plants in central Mexico. These are genuinely worm-shaped, soft-bodied larvae, not grasshoppers or ant eggs, and they have a distinctly different texture and flavor profile.

Red maguey worms are the more common variety and have a fatty, rich, intensely savory flavor — often described as smoky or meaty, with an umami depth that reflects their high fat content (they are among the most lipid-rich edible insects). They can be eaten raw (a practice that persists in some traditional contexts), but are most commonly prepared by lightly toasting or frying on a comal until crisp on the outside and melting within. They are consumed as a taco filling or combined with guacamole, adding richness and an unusual textural contrast.

Red maguey worms are an ingredient in sal de gusano — salt of the worm — a traditional Oaxacan condiment made by grinding dried red maguey worms with dried chiles and rock salt. This intense, smoky, savory seasoning is served alongside mezcal and used to rim glasses, season food, and complement the agave-derived spirit. Sal de gusano is available at Oaxacan specialty food shops internationally and has become a signature flavor component of artisanal mezcal culture.

The Mezcal Worm — A Marketing Invention: The single most famous insect associated with Mexico in the popular Western imagination is the "mezcal worm" — the larva that appears in the bottom of some bottles of mezcal (and is frequently, inaccurately, associated with tequila). This practice is not traditional and is not ancient. The mezcal worm is a maguey worm — typically a red chinicuil — and its inclusion in mezcal bottles was a commercial marketing innovation introduced in approximately 1950 by a Oaxacan mezcal producer named Jacobo Lozano Páez, who argued that the worm's presence was a quality indicator and added a distinctive visual element to the product.

The practice caught on as a novelty differentiator and became widely associated with Mexican spirits culture, particularly in the export market, despite the fact that traditional mezcal producers regard the gimmick with various degrees of amusement and disapproval. The regulatory framework for certified mezcal (Denominación de Origen Mezcal) does not require or endorse worm inclusion; indeed, high-end artisanal mezcals typically do not include it. The irony of the mezcal worm is that it may be the mechanism by which more Western consumers have engaged with insect consumption — the ritual eating of the worm from the mezcal bottle — than through any intentional effort to promote entomophagy.

Broader Mexican Insect Eating Tradition: Beyond chapulines, escamoles, and maguey worms, the documented Mexican entomophagy tradition includes ahuautle (water boatman eggs from Lake Texcoco, used to make a traditional tamale-like patty called torta de mosco); jumiles or chumiles (stink bugs from the genus Atizies, consumed live or roasted, with a distinctive iodine-like flavor from defensive secretions, associated with the town of Taxco in Guerrero); xaxes (ants, multiple species, typically roasted); and chicatanas (large flying ants of the genus Atta, harvested during their annual nuptial flights at the beginning of the rainy season, toasted with salt and lime, and used as a taco filling or ground into a salsa with extraordinary complexity). Chicatana salsa is considered a luxury ingredient in Oaxacan haute cuisine and commands premium prices at food festivals and specialty markets.

The market infrastructure supporting Mexican insect food is substantial. In Oaxacan markets, insect vendors are regular, established stalls — not novelty attractions. Pricing for chapulines reflects supply and demand dynamics based on harvest season, with fresh-harvest chapulines commanding significantly higher prices than stored dried varieties. The formalization of insect food commerce in Mexico includes export activity, with chapulines now available in specialty food stores across the United States and Europe.
