Moxyth

This creature is called Moxyth. It is a biomechanical moth set in the world of The Hunger Games. It is employed by the Capitol in conditioning the citizens therein. Moxyth deploys its poison by landing on citizens and brushing its finely barbed tongue against the skin, which injects an oxytocin serum. This serum strengthens the bond of in-groups, and increases defensiveness and animosity toward out-groups, partially explaining the enduring cruelty and enjoyment of the Games.
