The functional adaptations of these crystals and the colour of cocoons range from camouflage to heat absorption or light transmission [12]. Other wild silk cocoons, such as A. assama, also showed the presence of calcium oxalate crystal deposits on their surface [13]. The difference in the size and shape of the crystals suggests the role they might have on influencing the texture of the cocoon surface. Reeling of silk from Gonometa and other wild silk cocoon shells with these crystals is difficult due to their extensive infiltration between the silk fibers [14].
