Yes , a male Potanthus trachala .

A combination of three features help to ID this species.

1. FW spots 4 & 5 have no overlap with the spots above & below them, merely connected by the spikes.
2. HW combination spots 4 & 5 forming a block is strongly projected out from the upper margin of spot 3.
3. The abdominal end is strongly black-banded.

Male & female.

Yes, a female Caltoris cormasa.

This species have a redder tone to the UnH brown in photos. FW spots are yellowish.

The UpF shows a single cellspot ,which is stated to be usual, thus called the Fullstop Swift for the single spot.
However, many Singapore examples often have a second tiny upper cellspot.

Male have a rounder FW apex. Female a more pointy apex & a longer profile.
Two males , one female.

Female Telicota augias.

First thing is to ID the sex.
Female, longer profile shape, sharper apex, & abdominal end with a slight cleft.

Eliminating the possibilities.

Female T. colon: FW spot 4 & 5 not aligned , staggered like a stepladder (may be distorted); Face is paler.

Thanks, Dr Seow!

Confusion is very easy with poor shots & worn individuals.

Here is another that should be correct as a female T. augias.

This is a fine professional shot.
No problem here.

Male Baoris oceia.


Baoris is easily confused with Caltoris.
The FW is longer & more imposing, especially in the male ( ie. extending out more from the HW.).
The antennal shaft is mostly black, the pale area seen in some Caltoris is absent or obscure.
The HW often have a vague pale area around the cellend.
The abdomen is obscurely banded.


Caltoris cormasa male for comparison.

Baoris farri :Browner, lighter. More often with a full complement of spots.
Male FW less sinuous , the lower half margin straighter, less excavate.
B. oceia does not occur in China or India, so examples of B. farri from there are more reliable.
