Feldgeister ("field spirits"; singular: Feldgeist) or Korndämonen ("corn demons"; singular: Korndämon) are corn spirits from German folklore. Feldgeister often are also causing lightning and rain.
Numerous Feldgeister are known in German folklore, some shaped as animals, some in human form. The last grain heads and tree fruits are often left at their place as a sacrifice for the agricultural spirits. During harvest season Feldgeister flee deeper into the fields to escape the mowers. With the last cornstalks the corn spirit becomes trapped. Either it is killed by cutting the grain heads, threshing the corn or it is brought to the village in a ceremonial manner, shaped as a corn doll. Direct contact to the Feldgeist causes illness.
