Well, since I currently live in the southern extent of virginiensis 
country, I will say that P. virginiensis can be very common in the correct 
places, and that there *is* a bit of variability in the species.  You can 
get hints of black spots in the forewings, and underside veining as 
well.  The emphasis here, however, should be on the word "hints"!
