Chinicuil: what is it, history and how to eat the red maguey worm

What is it?

The chinicuil is the red larva of a moth (Comadia redtenbacheri) that lives inside the root of the maguey plant. It is one of Mexico's most prized edible insects and has been eaten since pre-Hispanic times. Its name comes from the Nahuatl word chīlocuilli, meaning "chilli worm" because of its bright red colour. Today it is eaten toasted, fried inside tacos, ground into worm salt to drink alongside mezcal, or used as a filling for hand-made tortillas.

Origin and history

The consumption of chinicuil is documented as far back as the 16th century in Fray Bernardino de Sahagún's General History of the Things of New Spain, which describes it as a ritual food of the peoples of the Central Highlands. To the Aztecs the chichilocuili symbolised the return of fallen warriors' souls, because the larva transforms into a butterfly. It is traditionally harvested between August and October, at the end of the rainy season, when the larvae reach maximum size before pupating. The states of Hidalgo, Tlaxcala, Puebla and Oaxaca preserve the millennial practice of its sustainable harvest.

Characteristic ingredients

The chinicuil proper is the larva of the lepidopteran Comadia redtenbacheri, distinct from the meocuil or white worm (Aegiale hesperiaris) which also lives in the maguey but in the leaves, not the root. It measures 4 to 6 cm and has a characteristic red or pink colour from the host plant's pigments. It is typically eaten with salt, lime, piquín chilli and nixtamalised maize tortillas. In worm salt it is ground together with coarse sea salt and dried árbol chilli.

Cultural significance

The chinicuil is one of the pre-Hispanic foods that best survived the Conquest and continues to play a central role in the gastronomic identity of central Mexico. It provides 60 to 75% high-quality protein and essential amino acids such as lysine and tryptophan, according to UANL studies. Its harvest sustains rural economies in Otomí and Nahua communities of Hidalgo and Tlaxcala. The FAO highlights it as an example of traditional entomophagy with potential for 21st-century food security, although overexploitation has made it vulnerable.

Frequently asked questions

Is chinicuil a worm or an insect?

It is the larva (caterpillar) of a moth in the family Cossidae. When it completes metamorphosis it becomes a nocturnal moth. Although called a worm, it is biologically an insect in its larval stage.

What does chinicuil taste like?

It has an earthy, slightly smoky flavour with notes of bark and agave. Toasted, it resembles a mix between pork crackling and walnut. It is the base of the famous worm salt drunk with mezcal.

Is it legal and safe to eat chinicuiles?

Yes. Their consumption is fully regulated in Mexico and they are part of the traditional cookbook recognised by UNESCO. They are sold in markets such as San Juan in Mexico City and exported dried to Europe.

What is the difference between chinicuil and meocuil?

The chinicuil is red and lives in the root of the maguey; the meocuil is white and lives in the leaves. Both are edible but chinicuil is more prized for its more intense flavour.
