Chahuis or xamoes are the common names given in Mexico to a variety of edible insects within the insect order Coleoptera. The insects' common names in English are often sticks worms, rhinoceros beetle, or just grub.
The chahuis insects feed on species of the Mesquite tree. Chahuis are consumed preferably in summer, in their last larval stage (2–3 weeks of life), since in their adult stage they have a bitter taste. They are consumed fried, roasted, stewed or in sauce, also tatemados al comal and served with salt and chili. In southern Mexico, they are eaten toasted on a comal or in a broth prepared with avocado leaf, epazote and ground corn.
Particularly appreciated are the larvae of the following families: Cerambycidae, Scarabaeidae, Melolonthidae, and Passalidae. In southern Mexico, they are eaten toasted on a comal or in a broth prepared with avocado leaf, epazote and ground corn.
