Tussar silk (alternatively spelled as tussah, tushar, tassar, tussore, tasar, tussur, or tusser, and also known in Sanskrit as kosa silk) is produced from the larvae of several species of silkworms belonging to the moth genus Antheraea, including A. assamensis, A. paphia, A. pernyi, A. roylei, and A. yamamai. India is the second-largest producer of tussar silk and the exclusive producer of Indian tussar (also known as tropical tussar), which is largely cultivated by tribal communities. Much of it is produced in Bhagalpur (where it is called Bhagalpur silk), Bihar, and the Malda district of West Bengal. Tussar silk is also used for Odisha’s pattachitra and West Bengal’s kantha embroidery. Chhattisgarh and Madhya Pradesh also contribute to tussar silk production. In recent years, the state of Jharkhand has emerged as the largest producer of tussar silk.
