Thank you Chuck for the reference to that thread. Elements of the thread are interesting and the mention of a "cline" in the species makes sense.
However, ultimately this one page thread still heralds the opinions of "splitters" and "lumpers". The thread is also over 10 years old so perhaps something more is now known.
I do not have the latest up to date (expensive book) on Ornithoptera (which came out a couple years back); so maybe in there something more is said about the modern ideas or systematics of Victoria.
Once again, thank you for looking up that thread.
I find that there are too many pages to look through (on some of the forum's categories) to perhaps find old and/or interesting discussions. My "hobby time" usually does not allow me to go back more than 10 pages.

A fine specimen indeed Hewi !
Those black hindwing spots are bold and well-defined and the extra gold spots are the "icing on the cake".
Well done.👍
Thank you for sharing.

What's the collecting location? I've seen hundreds or thousands of urvilleanus, no gold spots. Very unique. Chuck |

My "hobby time" usually does not allow me to go back more than 10 pages. I don't know the status of OV, it would be interesting to know if there have been any recent MtDNA studies done on them. Certainly, other studies on other species/genus have yielded amazing results with some shocking (to me) surprises. Adam and John have posted some great links to studies on modern genetics. It's my expectation that if mtDNA studies were done on OV, it would reduce the number of named ssp. Some of the ssp description papers I've read depend on morphological traits that in fact are neither unique nor common to the "ssp."; case in point, the FW apical blotch shape has been used to "differentiate" ssp, which is total rubbish. To find a particular topic (to see if it already exists) I use the search function, not dig through years of threads. Applying "lumpers" and "splitters" to forums, I am definitely a "lumper" in that I'd prefer to store and locate related discussions (e.g., everything about OV) in one thread. I see no reason to start a new thread if one already exists, and multiple threads make research more difficult and time consuming. You all have a great day! Chuck |

Genetic differentiation, particularly for the "barcode" gene, COI, will probably be minimal between populations of OV, particularly when comparing samples from not too distant islands. As far as I know there has not been a genetic study of victoriae itself, only studies of the birdwings in general which only include a few samples of each species.
Adam.
