Specimens collected May 19. Note highly variable dorsal ratio of black to red coloration but all five individuals display orange "editha line" on ventral hind wing.
The second photo is a diagram from Butterflies of the Pacific Northwest by Pyle and LaBar.
I've added a third picture to this observation with a comparison of Euphydryas edita (F) with an E. chalcedona (G) that I captured at the time I made this observation further inland: https://www.inaturalist.org/observations/25391714
I've annotated the editha line in blue on a duplicate set of ventral views. My understanding is that basically, using the black lines on the ventral hind wing as dividers, The colors on E. editha start at the outside edge and go "red, white, red, RED, white...." while E. chalcedona go "red, white, red, WHITE, white...." I've capitalized the color of the editha line.
BotPNW says E. editha: "On VHW the "editha line" runs through the red or orange postmedian band, splitting off little orange sub-spots".
For E. chalcedona it says "VHW "editha line" runs through yellow, not red."

Saw between 6-8 today along the road adjacent to the reservoir on Mill Creek. With all the veined whites flying I might not have taken a second look except that I had this butterfly on my mind after samela95437 recently posted one.
