Cricula Trifenestrata is a wild silk moth that naturally spins GOLDEN cocoons; they are abundantly found on specific regions in Indonesia and other parts of the world. Cricula larvae used to be labeled as pests as they ferociously feed on leaves of various fruit trees such as avocado, cashew, mango etc.


Fortunately since 1994, by collaborating with Japanese biotechnology and 'kimono' master craftsmans, supported by the Royal Silk Foundation (founded by Royal Family of Jogjakarta), we have managed to improve the local villagers’ income by successfully utilizing Cricula cocoons into export quality wild silk yarn and crafts; We transformed the local community's perspective of Cricula Trifenestrata from pest to quest.

  • "Batik" is a World Intangible Cultural Heritage, but imported fabric (silk) used to create this textile art was too expensive for the low-income batik artists (who are mostly women). Hence, endangering the art of "Batik" making, as less people in the region can afford to create "Batik".
  • There is an increase in using cheaper and unsustainable material for "Batik" making.
  • Fast-crop cultivation has created arid land in Imogiri, Yogyakarta, Indonesia; prone to natural disasters such as erosion, floods and landslides which endangers the Javanese cultural landscape, namely the Imogiri Royal Tomb of the Royal Family of Yogyakarta.
  • Cricula larvae was subjected as agricultural pests, massive noxious pesticides are used to cull this unique species, endangering biodiversity.


  • Low-income rural villagers, especially women and girls.

How do the building blocks interact?

A solution is made possible when people from different nations, cultures and expertise choose to openly collaborate and selflessly exchange knowledge necessary to solve a specific problem. A trusted leadership is paramount to maintain diplomatic relationships and guard the implementation of the solution, ensuring that it stays on the right path.


The Royal Golden Cocoon of Java: Cricula Trifenestrata is a manifestation of an aspiration from the Royal Family of Yogyakarta to improve the livelihood of local low income villagers and preserving the art of Batik and the cultural landscape; the Imogiri Royal Tomb.


The collaboration between the wild silk scientist and kimono master craftsman has created a dynamic economic value, creating employments and improving the livelihood of low income villagers. 


Jogja International Heritage Walk serves as a people empowerment activity where locals interact with international walkers, exchanging cultures and wisdom. This is a confident booster for the locals to continue learning and grow.


2019 was a triumphant year when the United Nations recognised our initiative as a good practice in line with UNSDG2030:

  • No. 5 Gender Equality: We have created working opportunities for women of all ages as wild silk yarn spinners; women empowerment as they regain identity and confident.
  • No. 9 Industry, Innovation and Infrastructure: We are pioneer in the innovation and utilisation of Cricula golden cocoons into wild silk yarns and crafts.
  • No. 11 Sustainable Cities and Communities: Strategically chosen afforestation area as the preservation of Cricula's natural habitat and Javanese cultural landscape, namely the Imogiri Royal Tomb of the Royal Family of Yogyakarta.

  • No. 12 Responsible Consumption and Production: By utilising Cricula golden cocoons, we have created a zero-emission business model. 

  • No. 13 Climate Action: Cricula Trifenestrata is polyphagous, this means they feed on a variety of host plants such as avocado, cashew, mango etc. Therefore, when we protect Cricula’s natural habitat by continuous tree planting, we are preserving Earth’s biodiversity; one of the paramount climate actions.

  • No. 15 Life on Land:  It is through continuous education that the villagers begin to understand the value of utilising Cricula golden cocoons, stop the killing and begin to protect Cricula’s natural habitat.


Royal Wild Silk Circular Economy #sdgaction30981

Under the creative leadership and collaborative spirit from the Royal Family of Yogyakarta, the Royal Golden Cocoon of Java: Cricula Trifenestrata is a successful initiative that showcases the possibility of international collaboration that create sustainable industry, tourism and afforestation while preserving a Javanese cultural landscape, namely the Imogiri Royal Tomb of the Royal Family of Yogyakarta.


By collaborating with Dr Hiromu Akai (Japanese Wild Silk Society) and Mr Hidenori Nakanishi (Master Wild Silk Craftsman), the Royal Silk Foundation (founded by the Royal Family of Yogyakarta) is the pioneer in utilising the Cricula golden cocoons into export quality wild silk yarns and crafts. Today, they are no longer treated as pests but a source of creative income when the wild silk yarn are crafted into high quality kimono and obi in Kyoto, Japan.


Jogja International Heritage Walk (JIHW) launched in 2008 is a one-of-a-kind sport event that involves walking as a healthy activity and a time of appreciation for the heritage sites; creating empowerment for the local villagers and refreshing cultural heritage knowledge for international walkers. We shall walk towards a peaceful world as we learn to understand and appreciate each others’ culture and heritage.


This initiative has also significantly created working opportunities for women of all ages as wild silk yarn spinners. With their skills to earn an income, they regain identity and confident as a human being. When these women have a strong sense of belonging and empowerment in the community; mothers have the voice and capacity in the family to protect themselves and their children from early or child forced marriage.


It is a triumphant year when United Nations recognised this initiative as a good practise in line with UN SDG2030. We are looking forward to create global awareness of this good practise, with the hope to replicate this practice globally, hence mitigating climate change.


We are pleased to have the blessing from the Royal Family of Yogyakarta, to further disseminate this good practice and accelerate global actions for climate change mitigation, beginning with the creation of a sustainable art book: The Royal Golden Cocoon of Java - Cricula Trifenestrata (Bilingual: English and Japanese), which will be linked to worldwide afforestation program.
