The Grand Imperial is rare,
and on Singapore island, mostly individuals are observed. In the
male, the upper surface is a shining blue with the apical areas black bordered.
The female is dark brown above with black and white markings on the tornal
area of the hindwings. On the undersides, the forewing and the costal
half of the hindwing are orange, with the rest of the hindwings white with
black markings. The species is remarkable in that its long white
tails are usually as long as the fore- and hindwings. The tails trail
elegantly behind the butterfly as it flies.
The Grand Imperial has recently
been found at one of Singapore's offshore islands, Pulau Tekong, and is
rather common on the island, where up to five individuals were seen in
one morning. The female appears to be the commoner sex. |
