Notes on some Butterflies and Natural History of the Siang Valley, Arunachal Pradesh

In July 2006, we had a splendid visit to the Siang Valley [also known as the Dihang Valley on some maps] in Arunachal Pradesh, northeast India, traveling on the 17th from Pasighat to Yingkiong and then over to Shimong village. On the 18th we attended meetings in Shimong, and then returned to Pasighat on the 19th. When journeying on the true right bank of the Siang, we were on the easternmost slopes of the Himalayas and in a tropical biome, the slopes lush with vegetation. Even where agriculture predominated, the primary color was green; only hamlets and very recent tracts of slash­and­burn agriculture showed brown.
