We are surveying moths of the super-biodiverse Siang river basin in Arunachal Pradesh. More than 500 moth species have currently been identified. At least an equal number of moth species are in the progress of being identified. The biodiversity assessment covers butterflies, moths, cicadas and odonates. Birds, too, are being surveyed, when the opportunity presents itself. We hope to use this assessment to initiate a conservation and livelihood program, involving local communities.
