I was just telling Ellen yesterday, yes, the male/female shot is of the Malayan Birdwing (Troides amphrysus ruficollis). The other species she mentioned is generally a montane species.

As for the Autumn Leaf, the markings are too variable. All the white spots on the underside are not too reliable for differentiation.

Yes, ssp continentalis (formerly known as siamensis) is known to occur in Peninsula Malaysia.

Thus far, the separation of the subspecies is not easy. But our local one (bisaltide) or what we previously called australis has five subapical white spots on the forewings. This species is currently known only from the Singapore Zoo, where it was bred on a plant near the Fragile Forest cage. Perhaps it's time to get some more specimens to compare.
