14’c Part Sun part cloud . Transect- Peterson Sagebrush Loop. Stopped for a rest between patrolling.. first time I’ve ever gotten close enough to a marble for a decent pic! iNat says large marble, and it was large cabbage white sized, but the upper wing whiteness and darker marks looked more like the pictures of desert in my books, and this is a sagebrush/grasslands hilltop
I believe the upper of the two individuals in the first image might be a Labrador Sulphur. I am uncertain what the lower individual is. Perhaps Christina Sulphur? This spot on Mt Helena had at least 20 Sulphurs flitting about. I took a lot of pictures- but most show them in a closed wing posture.
might be a gray comma? or an Oreas Anglewing?
