Butterfly on Bougainville
Sonoran desert
Congratulations on getting a picture with the wings open.
The dark lines across the edge of the wings suggests a sulphur butterfly. Furthemore, because there are no spots in the wings, it's probably a male sulphur.
I would initially guess a Clouded Sulphur or an Orange Sulphur.
