However the shape of the lower cellspot varies in all species.
There are image of C. aurociliata with two small round cellspots.
Others like C. bromus & cahira may also have a similar large elliptical lower spot with the upper one missing.
C. cormasa is common in Singapore but 99% of shots do not show the upperside.
Here is one by Sunny Chir.
It was tentatively IDed as C. bromus because of the twin cellspots, but the reddish UnH suggest it is probably C. cormasa. CORMASAPHTOBKT.jpg
Still a large lower elliptic cellspot seem the commoner form in C. aurociliata.
A positive ID is a side view showing the yellow cilia on both wings. It is the only species which can do that.
TL Seow: Cheers.
PS. I think you are right. It should be Caltoris aurociliata.
Although not the expected yellow-orange colour the cilia are sharply defined from the wing margins in this species.
1. C. furcztz.
The black area in space 1a is large & comes close to the margin
The large spot in space 1b is angled inwards.
2. C. bejaminii japonica.
The black area in space 1a is small & does not come near the margin.
The spot in space 1b is not angled in.
The tail is particularly short.
Evans state of C. benjaminii & furcata, the two black spots in space 2 (which is partially orange) are placed centrally ie roughly equal distance from vein 2 below & vein 3 above.
In C. stigmata the two spots are nearer vein 3 above & in C. xanthopogon they are nearer vein 2 below.
Can be hard to judge.
Upperside male C. benjaminii mostly green; C. stigmata & furcata, basally green;C. xanthopogon mostly brown.
