There were at least 3 moving around the tree. I believe they were ovipositing. White dots on leaf photos might be eggs.

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."

Little bloom on the hilltop; a solitary blooming manzanita kept this skittish insect occupied for a full three minutes.

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.

Puddling at the edge of the creek. Up Dexter Canyon at puddling site there are a scattering of wings from predated butterflies in the creek.

Brownish coloration and location would seem to rule out similar Western White.

Same individual I saw last week. Busy flycatching AND also caught what appears to be a tick (!) in the paved bike trail. Good bird!

Observed flycatching and being chased by Lark Sparrows and an Ash-throated Flycatcher. Flew mostly between largest oaks on left of parking area above dumpster (see last photo) and the small wishing-well-like structure on the right. Map/GPS is accurate, I checked ;-)
UPDATE: was re-found later that afternoon by Bill Pelletier. Ryan Phillips said it is the second record for the county.
UPDATE 7/30: Still there! https://www.inaturalist.org/observations/29897628

Female.
Found by Lisa Hug on an outing organized by David Rawlinson to this Sonoma Land Trust property.
Eventually saw about ten others. David says these are consistently seen here.

Male courting female; she is not receptive.
Females in this ideal spot perch on Star Thistle while males fly back and forth harassing them. Both sexes nectar on Star Thistle and Woolly Clover, and gravid females oviposit on Prostate Knotweed.

Image series show characteristic rotation of hindwings; a behavior that is thought to draw predator strikes to the 'false head' suggested by its antennae-like tails.

Quite a few between miles 1 & 2 of the Ridge Trail.
A worker we met doing a count here had found 53 partway through her transect.

Observed this fresh looking female and one other individual, a rather worn male.
