Pieris virginiensis vs. P. napi

[Bill Yule]

Hi all.
   I'm a little confused. I'd be interested in some of the current thinking about the taxonomic status of napi vs. virginiensis.  I know some folks don't consider napi a valid North American taxon and I know there have been times when virginiensis and napi may have been considered synonymous but what's the buzz on these taxa as far as New England is concerned from the point of view of you guys that have been around awhile.  What's a "Mustard White" called in Connecticut? Anybody collected West Virginia White in Connecticut(or anywhere) with a black spot on the dorsal forewing or is it always unspotted?

                                    Thanks,
                                                  Bill Yule
