If you fell asleep and didn't wake up when the first rotten corpse insect laid its eggs and ate your flesh and blood, in less than a few minutes, a continuous stream of flies would come to lay more eggs. In less than two hours, your body would be swarming with rotten corpse insects. Their saliva, secreted from their mouthparts, also has a paralyzing effect, so deeply sleeping people would not easily notice.
It must be said that the evolution of species is a very miraculous thing. Initially, rotten corpse insects were only the size of a pinhead, but now they can grow much bigger. In the later stages, they will become fat and plump, and due to the scarcity of food, they have become less picky about what they eat, consuming anything that holds energy.
