In human culture

In European folklore, the Roggenwolf ("rye wolf") is a carnivorous corn demon or Feldgeist, a field spirit shaped like a wolf. The Roggenwolf steals children and feeds on them. The last grain heads are often left at their place as a sacrifice for the agricultural spirits.

In contrast, the Roggenmuhme or Roggenmutter ("rye aunt" or "rye mother") is an anthropomorphic female corn demon with fiery fingers. Her bosoms are filled with tar and may end in tips of iron. Her bosoms are also long, and as such must be thrown over her shoulders when she runs. The Roggenmuhme is completely black or white, and in her hand she has a birch or whip from which lightning sparks. She can change herself into different animals, such as snakes, turtles, and frogs.

The classical scholar Carl A. P. Ruck writes that the Roggenmutter was believed to go through the fields, rustling like the wind, with a pack of rye wolves running after her. They spread ergot through the sheaves of harvested rye. According to Ruck, they then lured children into the fields to nurse on the infected grains "like the iron teats of the Roggenmutter ". The enlarged reddish ergot-infected grains were known as Wulfzähne (wolf teeth).
