Poludnica, Harvester of Souls
"Poludnica is a noon demon in Slavic mythology. She can be referred to in English as "Lady Midday" or "Noon Witch". She was usually pictured as a young woman dressed in white that roamed field bounds. She assailed folk working at noon causing heatstrokes and aches in the neck, sometimes she even caused madness.
Poludnitsa, who makes herself evident in the middle of hot summer days, takes the form of whirling dust clouds and carries a scythe or shears; most likely the shears would be of an older style, not akin to modern scissors. She will stop people in the field to ask them difficult questions or engage them in conversation. If anyone fails to answer a question or tries to change the subject, she will cut off their head or strike them with illness. She may appear as an old hag, a beautiful woman, or a 12-year-old girl, and she was useful in scaring children away from valuable crops. She is only seen on the hottest part of the day and is a personification of a sun-stroke." - Wikipedia
Japanese Mythical Spider Creature
"Jorōgumo (絡新婦 or じょろうぐも, Jorōgumo) is a yôkai with the form of a spider, that can change its appearance into that of a seductive woman when it wants to eat a human. Even when it is in its human form though, its reflection will show a giant spider. It can not be killed by any kind of poison. The name Jorogumo is that of the Nephila Clavata, a real kind of spider." - Yokai Wiki
