Most people imagine that the flies that swarm to a dead body are there to feed on the body. Not so, apparently. Their primary interest is in identifying a warm, sheltered, moist, dark place to lay eggs. The larvae then live on their surroundings until they reach the stage where they ‘migrate’ and find somewhere dry and safe to pupate. This also means that most flies around a corpse are female.
