You have beautifully captured the pictures of the brown caterpillar from different angles; the insect looks quite strange but beautiful.
You have observed very well that the insect becomes round when touched and moves by stretching its body. I was especially surprised to read the part where something green comes out of the insect's body. But what I liked most in the entire article was your human side. When the children were bothering the insect with sticks or trying to hit it, you stopped them and saved the insect's life - your love for nature is truly commendable.
