Dear Dr Seow, could you help to distinguish the gender of these 2 Common Rose? Butt A has rounder forewings and abdomen.

Both are males.
The two genders can sometimes be confusingly similar.
Male Pachliopta.
FW narrower with the termen (outer margin) straight.
Abdominal end, last segment is triangular .This is the clasper.

There is some variation in the wingshape & some males have broader FWs, but the termen is always straight in the middle part.

The male is much commoner.
TL Seow: Cheers.
