Maguey Worm / Chinicuil

What it is

The larva of the Comadia redtenbacheri moth (red maguey worm) or the caterpillar of the Aegiale hesperiaris butterfly (white maguey worm), both living inside the stems and roots of Agave (maguey) plants in central Mexico.

Red chinicuil (Comadia redtenbacheri) is the more commonly consumed and commercially significant variety. White chinicuil (Aegiale hesperiaris) is less common.

Cultural significance

Pre-Columbian, documented in Aztec sources. The association with mezcal and maguey plants connects the maguey worm to one of Mexico's most culturally significant food and beverage traditions. Sal de gusano is among the most requested Oaxacan specialty food exports.

The Mezcal Worm Note: The larva placed in some commercial mezcal bottles is a red chinicuil — a marketing innovation from approximately 1950, not a traditional practice. Artisanal and premium mezcal producers generally do not include it. The FDA in the United States has technically classified insects in alcoholic beverages as "defects," though enforcement against the mezcal worm has not been pursued given its deliberate inclusion.

Food uses & preparation

Larvae are extracted from within maguey plant tissue — they bore into the stems and root crowns where they develop, consuming the plant's interior. Harvest requires splitting or cutting the maguey to access the larvae. They can be eaten raw (traditional in some contexts), toasted on a comal until the skin is crisp and the interior renders into rich fat, or fried. Also used to make sal de gusano — ground dried chinicuil mixed with salt and dried chile — the traditional Oaxacan condiment served alongside mezcal.

Rich, fatty, intensely savory, with smoky and earthy notes developed during toasting. The red maguey worm is among the most lipid-rich edible insects, producing a self-basting quality during cooking. The flavor has been compared to bacon or rendered lard — fatty, meaty, umami.

Taco filling; ingredient in guacamole; primary ingredient in sal de gusano; occasional use in mezcal bottles (see marketing note above). White maguey worms are sometimes prepared in green salsa or as a garnish.
