Nymphalis californica
The wings of California Tortoiseshell butterflies have ragged, irregular edges. The upper side of their wings are orange with blacks spots and a wide black margin. The underside of their wings are a mottled dark brown that has a bark-like appearance.
I had this California Tortoiseshell butterfly nectaring on blooming Fragrant Sumac up in a far northern Utah desert in my viewfinder four years ago today.
On a recent trip to the West Desert sky island mountains in Tooele County I found my lens pointed at trees, shrubs, wildflowers and a butterfly.
