Canadian Tiger Swallowtail

Please know that BOTH Eastern (Papilio glaucus, widespread) and Canadian (P. canadensis, much less so) Tiger Swallowtails are reported for Ontario and potentially occur in Port Stanley . . .

No problem Candice. Thanks for the great caterpillar shots. Its always good to put my ID skills into practice. Beautiful spottings.

Thanks so much bee.jacbs! Yes it looks a lot like the canadian tiger swallowtail, thanks for the I.D :)

Hi Candice. Great caterpillar, and I love all the angles you were able to get. The other species this could be is the Easter Tiger Swallowtail. The ID book I have says that the two are indistinguishable as mature larvae. I'm guessing based on your location that it is more likely to be the Canadian Tiger which replaces the Easter Tiger in the north. Keep up the great spottings!
