4 cm in length. Found crawling on the ground. This species is green and starts turning into this brown colour when they are ready to pupate.

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:http://bugguide.net/node/view/575468/bgimageThanks again for your help and any insight you can give me on your ID.Mardon

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 BugGuide.net (the one I referenced above). That was just a lucky break. :)
