I can not figure out how to post the pics in the correct order.
She (judging by the size of 5.5 cm) was retracting the osmeteria.

I swapped them round for you, so now they are in the correct order.

Great photos!

I also have a problem posting pictures in the correct order. I usually have to post them in reverse order (last one first) in order to make them appear in the correct order. Adam, how do you swap them around?

Click the button that says "Full Editor & Preview" and you can see your post before you submit. That shows you which order the photos are in. Then you can copy/ paste to rearrange.

The osmeterium of P. cresphontes is bright red. Is the color difference with rumiko consistent?

I cannot tell if the color difference of osmeterium between P. rumiko and P. cresphontes is consistent. The color pattern of the adult specimens I could carefully observe matches the one of P. rumiko, given by Shiraiwa et al., 2014. That's why I assume the larvae of the "Giant swallowtail" in my area (Carlsbad, CA) belong to P. rumiko. I often find larvae on citrus trees in my backyard, and I can’t remember one with red osmeterium, though this is just an observation, not a statistic. Unfortunately, I could not find any information on the osmeterium color in the Shiraiwa paper.

Yes, based on your location, you have rumiko. All the cresphontes I have seen have bright red osmeteria.

This is not only based on the location. As I said, the morphology of the butterflies corresponds to
the description of P. rumiko. I read the paper again: the morphology of larvae also matches
P. rumiko. Perhaps, the color of osmeterium is diagnostic.
