Your caterpillar is a Western Tiger Swallowtail (Papilio rutulus)

Hi Marcel,  

Thank you for your feedback.  I'm sure you know a lot more about Newfoundland's many animal creatures than I do but I'm curious about your ID of Papilio rutulus versus my thought that it is Papilio canadensis.  Can you give me any insight into what shows this to be a Western Tiger Swallowtail rather than a Canadian Tiger Swallowtail?

Here's a Papilio canadensis image that to my eye looks just like mine:

Thanks again for your help and any insight you can give me on your ID.

Actually, you are right. There are no Western Tiger Swallowtail in Newfoundland that I am aware of.

Thanks again for commenting.  I can use all the help I can get on the ID side of things.  The only reason I knew this one is that I had found that image on (the one I referenced above).  That was just a lucky break. :)
