In Aztec mythology, the Civatateo were vampires. They were noblewomen who died during childbirth and, after returning to the land of the living, stalked travelers and haunted temples. They were shriveled and pale. Their faces are white, and their hands and arms are covered in ticitl (a white chalk). Their tattered dresses are decorated with crossbones.

Civatateos are servants of the Aztec moon deities Tezcatlipoca and Tlazolteotl.

They can be prevented from attacking the living by placing food on shrines built at the crossroads. Their favorite offering is a cake in the shape of a butterfly.
