“Soon, in the pink dusk, the shadowy figure would bow forward, sighing, and the flies settle once more.”
This describes the dead parachutist moving in the wind, creating the illusion of a living beast. It symbolizes the boys' misunderstanding of fear and reality.
The "flies" settling on the parachutist connect to the book’s title, Lord of the Flies, reinforcing the theme of death and decay.
This misunderstanding will fuel chaos in the next chapters, as Jack uses the "beast" to solidify his power.
