I'd guess these two were mother and her yearling.
Saw many (counted about 12) over a few hours of hiking, but could not get a photo. Unfortunately (for the butterfly) the crab spider made these photos possible.
male flowers and first leaf.
Large group at a seep area.
About 40 individuals here.
Large stand of this flower on a rocky hillside.
Wouldn't open those lovely blue wings for me, but I think I have this ID correct.
Saw 2 other pair in muddy seeps along this path as well.
Couldn't get a clear photo for this one.
One from a flock of about 20. Along entrance road to park.
