This checkerspot was hopping between Hookers Balsamroot flowers.
I didn’t notice the Yellow Crab Spider on the yellow petals until I processed the picture.
Too fast to get an underwing shot but with the red band on the upper hind wings, I believe Edith’s is right.
Found this ant, will upload photo of ant shortly
I found it under the wheel of my car, it was missing a wing when I caught it.
