Was expecting it to be much bigger for it to be name the large dart.

It is possible for an individual to be larger or smaller than the norm for the species.

For this individual, the shape suggest a small species.

There is a prominent black band at the abdominal end.
There are 3 full subapical spots.
FW spot 5 is smaller than spot 4.

Only 4 species in Singapore have a black banded abdominal end.

1. Potanthus trachala. FW 14 - 15 mm.
FW spots widely separated ,spiky.
Male & female.

It is probably Potanthus mingo female.

I suggest for Potanthus, show at least two images as small details matter.
