An interesting caterpillar stays inside this cocoon. They build their cocoons inside a wall of twigs arranged together. These twigs are wound together with the help of a silk like fiber. Inside which the caterpillar pupates. The construction of the cocoon shows some level of intelligence where the small twigs are arranged in a wall and one is leveled at a distance while the opposite side the twigs are protruding outwards. When we open this cocoon it shows that the caterpillar inside is a tender one. And has now other protection. A species of moth builds its cocoon this way.
