Creating my own folklore (Greek Mythology)

Greek: Arachne - If you kill spiders for no reason, Arachne will come out of her web in the sky, leave you in a web and then poison you so you slowly die. Once this little boy killed a family of spiders, which Arachne saw it and decided that she would come out of her web and hunt him. She led the boy into her giant web and then webbed him up. And poisoned him so he would slowly die, so she could eat the corpse.
