Can't say for sure, Scott, but probably not. I'd keep Papilio demoleus for that smaller caterpillar since it's your most common swallowtail.

Hi EarlyStages/Kieth. Would you also say that the page I have linked to this spotting, namely is also Papilio ambrax? Thanks

Dear Mr. Frazier,

Greetings from a lepidopterist who studies the immature stages and hostplant utilization of butterflies in order to better understand their scientific placement. I am excited to report that this is NOT a Papilio demoleus larva, which in its darkest form does appear similar, but rather something much more unusual. Thus, hoping to accurately identify your caterpillar and also aid my research, please contact me at Thanks and best wishes!
