Before reporting our observation on cocoon morphology, it is useful to look at the historical background to cocoon studies to give a general overview of cocoon characteristics. In the late 19th and early 20th century, the biologists observed and recorded the behaviour of different silkworms and the appearance of cocoons produced in a biological perspective. But in the last ten years, material scientists moved on to use silkworm cocoon as a model of biological composites by studying their morphology, structures and properties using advanced techniques such as SEM, DMTA etc.
