Cocoons of Chinese silkmoth
Two cocoons in process of being spun by larvae (caterpillars) of the Saturnid silkmoth, Samia cynthia. The cocoons are anchored to twigs of common privet, Ligustrum vulgare, and each will eventually contain a pupa. In the picture, the larvae are discernible, most clearly in the upper cocoon (green and yellow, head uppermost). Silk is produced from two components, fibroin and sericin. The diameter of each strand is approximately 15microns, and each final cocoon will contain several hundred metres of silk. S. cynthia is one source of wild silk". Commercially produced silk is made by a different moth, Bombyx mori, an entirely domesticated species unknown in the wild. S. cynthia is native to Central and Eastern China, but is now also found in parts of Europe and the USA following importation. Each cocoon is approximately 5cm long."

EDITORS COMMENTS
This print showcases the intricate process of silk production by the larvae of the Saturnid silkmoth, Samia cynthia. Two cocoons are delicately being spun by these caterpillars, firmly anchored to twigs of common privet. Each cocoon will eventually house a pupa, representing nature's remarkable transformation. In this image, one can observe the discernible larvae within the upper cocoon, adorned in vibrant shades of green and yellow with their heads positioned upwards. The silk produced from these cocoons is composed of fibroin and sericin, two essential components that give it its strength and lustrous texture. Remarkably thin strands measuring approximately 15 microns in diameter make up each strand of silk, with several hundred meters contained within each final cocoon. Samia cynthia is a species native to Central and Eastern China but has since expanded its presence to parts of Europe and the USA through importation. Unlike commercially produced silk made by domesticated moths like Bombyx mori, S. cynthia represents a source of wild silk. This stunning photograph not only captures the beauty and intricacy involved in this natural process but also serves as a reminder of how different species contribute to our world's diverse ecosystems. It highlights both scientific curiosity and appreciation for nature's wonders while offering an opportunity for further exploration into the fascinating world of silkworms and their remarkable creations.
