[1] [2] [4] Hairs from the caterpillar are incorporated into its silken cocoon. [5] The cocoon becomes black and shiny with yellow markings and the pupa will stay like this for 12 – 35 days. [4] The length of pupation is largely affected by temperature and the humidity also has an effect on the pupal survival.
