Lip Bug is a leech, usually brightly-colored, covered in mucus secretions, with the front part of its body resembling a pair of human lips.


Lip Bug is a type of insect which consumes human vocal cords and imitate the voice of its victims. It takes practice for someone to be able to tell the difference when these bugs were most energetic based on the change in color.[1]
