Dear student

When caterpillar of silkworm moves to next stage of pupa it weaves
a net and make side wise head movements During this movement it
secrete a fibre which is made up of protein This fibre hardens when
exposed to air and becomes silk By the movements and constant
secretion of fibre, pupa covers itself completely by silk fibres
and cocoon is formed
