 Besides，I also have a male one from Bulolo PNG，and quite diffierent from ssp.gabrielis. It looks more like ssp.autolycus. Are the two ssp both distributed in bulolo？ |

Subspecies gabrielis is very dark and only occurs on the Admiralty Islands (Manus), not Bulolo. Specimens from Bulolo are autolycus. The specimen supposedly from Manus in the photo above looks like autolycus, the data must be incorrect. The Trobriand Island ssp. is telemachus but your specimen also looks like autolycus. Ssp. telemachus has a smaller blue patch on the hindwing. I think that the problem probably comes from the data on these specimens. Here's a photo of males of gabrielis, autolycus and telemachus so you can see the difference.  Adam. |

I mistrust material rubber stamped Bulolo. That was a central clearing point and i think unlabeled specimens got the Bulolo stamp. Note that many Bulolo specimens have no date on the envelope

Are those different shades of blue just variation or specific colours to certain subspecies?

Old world / new world, out of this world. Is long as it is in North America, I am good!!
I attempted to count the subspecies on Adams post. And I thought the number of subspecies of Speyeria cybele was outrageous.
I am surprised no one came up with nexttwolasti....

There is a big difference between subspeciation in North America and SE Asia/Australasia. The reason there are so many subspecies is because of the large number of islands across the region. Many butterfly species have become isolated on each island and over time have diverged into distinct subspecies. Of course there are also other species that can fly between the islands and these do not subspeciate at all, or only form distinct subspecies between different island groups.
