The Blue Nawab (Polyura schreiber tisamenus)
The Blue Nawab has a silvery underside marked with brown and purple patterns. The upperside has a white median band ornamented with blue. It possesses two pairs of tails on the hindwings. The female of the species is usually larger often attaining a wingspan of 80mm, with broader and longer tails.
The species has a robust body, and like a typical Nymphalidae, has only four fully-developed legs for walking. The forelegs appear more brush-like and are not used for walking.
Unlike the Plain Nawab, the Blue Nawab does not display territorial behaviour where it perches on a few favourite spots and returns to those spots time and again after chasing away intruders. Where observed, the Blue Nawabs are almost always in full flight, as if in a hurry to go somewhere.
