In the book the butterfly symbolizes the people of Sealand, because they are free; free from fear, ignorance.
It Also symbolizes the butterfly is the face that they are beautiful, both mentally and physically, untouched by fanatical killing or sterilization of people who are “different”.
The group, David, Rosalind and Petra in their escape to Sealand, are like insects leaving behind their crawling caterpillar, existence to emerge from their chrysalis as, beautiful, and free-flying butterflies.
The Chrysalids symbolizes the change in human nature, and human survival techniques.
We beg thy forgiveness that we have not better instructed this child in thy laws......" (27).
In addition, the people of Waknuk feared the people of fringes.The telepath group could also be seen as the intermediate stage between the people of Waknuk whose fear of the pat has led to primitive, non-developing society and the people of Sealand, who have progressed.The fourth and last stage, the butterfly, represents freedom, because it is able to fly, to see large areas from the sky, and is beautiful.It is a stage in which the insect appears dormant and unmoving, but changes are taking place inside which enable it to emerge from the chrysalis as a more advance form of life.John Wyndham chose the title The Chrysalid because of the human life and survival many centuries after the all out nuclear war or “Tribulation” had occurred, which in many ways relates to the butterfly life-cycle.Many authors use reflective themes to express their opinion on an ongoing event.A novel is usually based on several themes that represent author's views on a certain thing.The second stage, the caterpillar stage, represents a confined life, as the larvae do not act individually.If the caterpillars do not complete the butterfly’s life-cycle, they will eventually die.The egg symbolizes the reemergence of life on Earth or in Waknuk after the Nuclear War, or “Tribulation”, had occurred.It may also mean the rising of the Waknuk Society, raised by Elias Strorm.
