I think it is likely to be brevicauda from the wing shape. The black centre to the anal eyespot is rather variable in brevicauda, sometimes like this and sometimes connected to the margin. It's a pity you don't have locality data. Is there any particular reason you think it might be a hybrid? Perhaps a photo of the underside might have some clues. Adam. PS.

Personally I use imgur.com for photo hosting, as they provide links to display photos pre-formatted for the forum, but your shared Google drive photo is visible.

Thank you for your response, and I just got some more information on its locality and that it is from Rivière-au-Tonnere on the northeast coast of the St-Lawrence river in the Quebec Province and I got some responses from other people who thought it was a hybrid because of the slightly longer than average tails it seems when compared to other brevicauda. Sadly that is the only picture I have but I just wanna know if it could be papilio brevicauda brevicauda or some subspiecies or a hybrid with polyxenes if polyxenes is also found in that area. Thank you for your help

Hello Adam, I could not find P. brevicauda in your last book from Makoto Nakae, any reason ? A+, Michel

Thank you for your help Rivière-au-Tonnere is in the distribution area of ssp. brevicauda, not far west of Havre-Saint-Pierre where my specimens came from. The tails do not seem unusually long, but they are not as short as some specimens. As far as I know polyxenes does not occur in that part of Quebec. Hello Adam, I could not find P. brevicauda in your last book from Makoto Nakae, any reason ? A+, Michel Makoto Nakae treated brevicauda as a subspecies of machaon rather than a separate species.
