CHIN'S BUTTERFLY GALLERY ~ LIFE HISTORY ~ THE BLUE NAWAB
The Blue Nawab

LATE ONE AFTERNOON in February 2020, while weeding my overgrown garden in Puchong, Selangor, I found a green chrysalis hanging from an Aloe vera leaf. Carefully, I cleared the weeds around that neglected pot of Aloe vera and I also pulled off most of the plants so that I could carry the pot indoors without jolting the chrysalis. At that time, I did not know what species it was but I was quite prepared to wait for the adult butterfly to emerge as I had previously bred out caterpillars of some other species.
  The butterfly emerged three days later, and to my surprise it was the Blue Nawab (Polyura schreiber), which I had believed then was primarily a forest-dwelling species. It was also the first time that I see this species after several decades of butterfly watching since the 1980s.
  I learned from my references that this species inhabits inland forests at low to moderate elevations and also in villages near forests. The host plant is the rambutan tree. Yes, I have a rambutan tree but it is at other end of my garden, more than 30 feet (10 metres) away.
  Elated by this find, I posted my story and some photos on Facebook and the posting received an enthusiastic response. An avid butterfly watcher living in Singapore, Mr. Teo Thiam Peng (also a Facebook Friend), had bred this species on Red Saga (Adenanthera pavonina), and he posted some of his own photos.
  Using some of Mr. Teo's pictures (with his permission of course) and some of mine, I have put together this photo essay to give you (visitors to this website) a glimpse of the life history of this beautiful species.
  The Blue Nawab is found in India to Thailand and other parts of Southeast Asia, including Sumatra, Borneo, Java, Pahlawan and the Philippines. The subspecies found in Malaysia, Singapore and southern Thailand is tisamenus, in northern Thailand and India it's assamensis.
