Chicago Mantis is a creature reported in August, 1999 from Illinois.
A man visiting a friend’s house and sleeping on the sofa in the bedroom suddenly woke up feeling very panicky and totally unable to move. Looking towards the front door he saw a huge humanoid figure over 7 ft tall standing by the door. The figure resembled a large “praying mantis” and was wearing something resembling a black and purple cloak. Its skin was dark gray in color. It slowly approached the witness and reached out to him with a large hand with long thin fingers and grabbed his shoulder. At this point the witness lost consciousness and does not recall anything else of the incident. He remembered also feeling very cold during the encounter.
