Picture one. Two male nominate subspecies. East Java
Picture two. Pair of Troides amphrysus kottovae. Banggi Island, Sabah, East Malaysia(Borneo)
Picture three. Pair of Troides amphrysus flavicollis. Crocker Range, Sabah, East Malaysia(Borneo)

This species is my absolute favorite amongst the Troides. T. prattorum from Buru is almost as spectacular for the pearlescence which it has on the hind wings.

However, in my humble opinion the variable yellow splashes/streaks on the forewings of this species (males) give it my nod for "top dog".

Really nice specimens Dave !

Thank You Trehopr. These are all from Ken Thorne in Canada
Could not agree more with what you say about the beauty of this particular species. Think the males of the nominate subspecies are really spectacular.
I have an old pair of T prattorum. That's a lovely one too as you say.
