Witch (or Naletnica, Sihirbaza)

According to a Bosnian belief girls become witches if they wish to cause someone harm, for example, to get revenge on her neighbour, her neighbour's cattle or children. Witches drink children's blood and they take away the milk from cows. While a Mora stops being a Mora as soon as she gets married, the same thing does not apply to witches. They don't lose their title after marriage because they stepped on the Holy Qur'an and they gave their souls to Iblis.
The witch can turn into a large butterfly and enter any house she wants especially the one that has small children in it. When you notice such a butterfly in your house, you must catch it and burn one of its wings on a candle uttering: "Come back tomorrow, I will give you salt" and then let the butterfly out of your house. It is believed that the first woman that comes to that house to ask for some salt is a witch. If she is then told that she visited this house during the night in a form of a butterfly and that she is a witch it is believed that she looses all her demonic powers.
