--000000000000d2f6ca05f52a18a1 Content-Type: text/plain; charset="UTF-8" marginalis (or at least populations thought to be that species) is geographically variable to the point that one verbal description or one illustration won't capture the situation. But in the geographic area where marginalis overlaps with oleracea and angelika; the best way to recognize them is to look at and compare the dark scaling along the ventral hindwing veins aka vein borders. The difference in appearance is well illustrated in this graphic: https://flic.kr/p/QPSrQw and the northern specimen comparisons I have shared. I cannot improve on that by dreaming up words. I will leave the translation into words to those who have superior wordsmithing skills I do not know of a place where all white summer specimens of oleracea fly with all white summer specimens of marginalis. But if such a place is discovered, that would present a bit of a challenge that would require some work to sort out. The spring adults would be plainly different so that should be doable. There are a fair number of images of these species in my whites album on flickr that would help develop an identification 'gestalt' https://www.flickr.com/photos/118126948@N03/albums/72157659975461930 Here is another female comparison, using even older pics than the ones shared recently: https://flic.kr/p/25iMHd3 On Mon, Feb 20, 2023 at 10:40 AM <tlpyle...> wrote: > Norbert, > > For the poor field guide writers amongst us, how would you tersely > characterize the observable, reliable differences between these three > species that allow you to encounter them all together and distinguish them > with confidence?
