Great stuff, and thanks to you and Jan for the Straatman story.
Note that the vandepolli (no 'r' in the name too) photo is upside down.

Thank you for your contribution to this forum. It is so nice to learn more about the man behind the legend. You should add this to WIKIpedia.

Papilio 28570 Thanks for the positive feedback. I should like to add the information to Wikipedia when I find time.
jb. Welcome to the forum. You are lucky to own a historic female O. meridionalis from the Brown River collected by Ray Straatman. Can you show the male above with its data, also from the Brown River? Unfortunately the Brown River and adjacent O. meridionalis populations are long gone, a victim of industrial logging.
Peter.

Dear nomad,
I also thank you very much for your effort, to sharing with us so invaluable information contained "papers".
I have two questions. Mr. Straatman wrote regarding O. alexandreae :"However, within its range there are many areas where the butterfly does not occur although the hostplant grows
prolifically."
What could be the reason for not occuring in that areas within its range, when there growth its hostplant also?
Mr. Straatman wrote, that breeding O.alexandreae on Aristolochia tagala make its developement nearly one month shorter than on A. schleckeri. And A.talaga is widesprread in that area where O. alex. occurs. So what could be the reason, that the nature has conditioned O.alex. on A.schleckeri, and why the developement takes so short on tagala?
I am sorry for my english. I hope I am understandable.
Thank you again.

Hi memo
I am pleased you enjoyed the O. alexandrae Ray Straatman paper. The taxonomists have been hard at work with the Aristolochia hostplants of the Ornithoptera and have put now put some of these in the genus ' Pararistolochia'. It apparently was first discovered by Parsons [1996] that the main foodplant of O. alexandrae was not A. Schlechteri but a new species that has been named Pararistolochia alexandriana and that in the wild this butterfly will also utilize another new species Pararistolochia meridionaliana [ foodplant of O. meridionalis].
The reason O. alexandrae chooses the A. Schlechteri [ now P. alexandriana] of Straatman is probably certainly as the Author mentions hereditary. It is interesting the larvae grew much faster on A. tagala but will not ovaposit on this plant in the wild.
Although the hostplant may occur thoughout the small range of O. alexandrae this species is known to inhabit areas where there are microclimate environmental conditions that suit its needs. Even back in the 1970's Ray Straatman and Jan Pasternak who studied this wonderful butterfly mention they saw few adults and it was nowhere common.
Anthony, I am glad you found this a fitting tribute to a great lepidopterist.
Peter.
