This is a grim one. Fortunately for us, it doesn't happen anymore; but in 401 BC, a form of insect torture named scaphism was used to punish criminals. A soldier named Mithridates was one unfortunate soul to die this way, after embarassing his king, Artaxerxes II, by boasting of killing his rival, Cyrus The Younger. He was locked between two rowing boats, forced to ingest milk and honey to the point of diarrhoea, covered in yet more honey (with special attention devoted to the face, genitals and anus), then left for insects to consume. Mithridates survived 17 days of this insect torture in a putrid death-boat of his own feces, before eventually dying of a combination of dehydration, starvation and septic shock. Okay, you can puke now.
