Eastern/Canadian Tiger Swallowtails

[Paul Opler]

     All, There was an excellent article on this species situation by Mark 
     Scriber in the American Entomologist last year or the year before.

In addition to James Adam's suggestion, try checking out the original 
paper which splits these taxa (if you havn't seen it already): 
     
Hagen, R. H., R. C. Lederhouse, J. L. Bossart and J. M. Scriber. Papilio 
canadensis and P. glaucus (Papilionidae) are distinct species.  J. 
Lepidopterists' Society. 45: 245-258. 1991.
     
Based on years of research, this paper presents a pretty convincing 
argument for the recognition of P. canadensis as specific. 
     
Best,
John
