The cocoons of the Saturniidae wild silkworms are filled with 0.1- 0.8 micron small pores; first discovered by Professor Dr. Hiromu Akai in 1988 with an electron microscope. Cricula Trifenestrata is one of the wild silk moths that belongs to the Saturniidae family which has the highest number of pores (only 2nd to the protected Agama Miley Madagascar) and occured in abundance. Presently, they are still labelled as pests in Indonesia and the rest of the world.
Unlike the domesticated (non-porous) Bombyx Mori silk yarn, porous wild silk yarn has excellent heat retention, light texture, higher UV cut and bacteriostatic properties; the potential "healthy silk" of the future.
Therefore, Cricula Trifenestrata golden cocoons can be utilised as sustainable and biodegradable materials which is healthy for human and the environment:
- TEXTILE: Cricula wild silk yarns and textile are anti-UV radiation & antimicrobial.
COSMETIC: Cricula proteins are natural, non-allergen ingredients with high anti-UV radiation & excellent antioxidants; great for healthy skin.
PHARMACY: Cricula golden pigment is rich with Lutein; a type of carotenoid pigment contained in the cornea of the eye, effective against cataract. (patented in 2008)
There is no Cricula Trifenestrata wild silk moth in Japan, however Japan has the scientific knowledge and biotechnology for producing Cricula Trifenestrata wild silk healthy anti-UV beauty powder which are best-sellers in Japan and Thailand, since circa 2010.
WHY? Today, MORE THAN 30 YEARS LATER, Cricula Trifenestrata is still labelled as PEST in Indonesia and the rest of the world. Presented at ICCROM International Climate Culture Peace Conference 2022. Link available on UN SDGS website.
