Antheraea paphia (L.)
Tropical Tasar Silk
This type of wild silk has been exploited for hundreds or possibly thousands of years in eastern India, from the Himalayas down to the southern areas of the Indian Peninsula, particularly in the Deccan Plateau. The moth is known scientifically as Antheraea paphia (Linnaeus), and the synonym Antheraea mylitta (Drury) is still often used in literature. The caterpillars live on many trees, but especially on Indian dammer (Shorea robusta) and various species of Terminalia, like the white murdah (T. arjuna) and laurel (T. tomentosa). The Hindi names for these three trees are sal, arjun, and asan, respectively (Jolly et al. 1974, Mohanty 1998).
Tasar culture is important to many of the Tribals in Bihar, Chhattisgarh, Orissa, and Madha Pradesh. Cocoons are collected in the field. However, eggs are often placed onto trees near villages and larvae are moved from one small tree to another if they defoliate the first, so a certain amount of husbandry is done for what is otherwise a wild silkworm. There are numerous so-called eco-races that produce huge cocoons varying from brown to gray to dull yellow, and most of these eco-races are restricted to certain regions and feed on certain kinds of trees. The silk is reeled to make saris, scarves, wrappers, and it is spun to make heavier scarves and wrappers. Tasar silk has a special cultural significance to all segments of Indian society, and tasar kurtas are often worn by grooms and tasar saris by brides at their wedding ceremonies. The undyed natural brown or beige is generally favored for traditional textiles and garments. Many of the famous ikats from Orissa and embroidered and brocaded wrappers from West Bengal and other eastern states are made of tropical tasar silk. Because tropical tasar silk has been over-exploited in India, a lot of Chinese tussah is now imported to serve as a substitute on the handlooms (Srivastav & Thangavelu 2005). Spun or reeled fabrics of mulberry silk are also often dyed a light brown to look like tasar. Silk of Antheraea (tussah, tasar, muga) appears under magnification as flat strands like tape or ribbons. However, eri and mulberry silks have fibers that are more slender and appear rounded in cross-section. A dissecting microscope shows these differences quite well, but a good hand lens or a loup like is used to view 35 mm slides may suffice to distinguish mulberry from those made by Antheraea.
