UV-exposure is the major form of peroxidative insult encountered by this wild tropical silkworm. Our in vitro study also strongly supplements the in vivo findings indicating S. robusta foliages as a strong inducer of lipid peroxidation (LPx). Adults are occasionally seen attracted to lights during spring and early summer, a common habit of many moths. These silkworms live in the wild forests in trees belonging to Terminalia species and Shorea robusta as well as other food plants like jamun and oak found in South Asia, eating the leaves of the trees they live on. Peigler focuses his research primarily on the taxonomy, phylogeny and biology of wild silkmoths (Family Saturniidae) of the world, particularly ones from eastern Asia.

The silkworm rearing and grainage performance being important for sustenance of tropical tasarculture, the cocoons generated on Lagerstroemia parviflora food plant were analyzed for economic viability in comparison withTerminalia tomentosa plant. The life cycle comprising five larval stages and the cocoon stage lasts for about 30–45 days. The plant and cocoon compounds were anti-oxidative as determined by bleaching of beta carotene in vitro. Oak tasar silkworm exhibits weak bivoltinism and is a semi-domesticated lepidopteran. The castor silkworm which produces Eri silk is reared on the castor oil plant.
