Common Batwing (Atrophaneura varuna varuna)

I came across this "Batwing" aka the "Common Batwing" recently in a Northern State of Peninsular Malaysia. According to a local expert (i.e Nlliew), this is an uncommon and seasonal butterfly which abundance may fluctuate according to certain years and in certain locality.

This one here was not puddling on the ground but was more comfortable resting on some leaves deep inside the forest.
