I have spent hours searching the Internet and your site and the Holland book you recommended. Two of the attached pictures are of a moth with its wings open and closed; I though perhaps it could be a pine moth. The other picture (sorry it is a little fuzzy) is of a beautiful moth 3-4 inches in size. Any help is appreciated. These are taken near Prescott, Arizona in a pine forest. Love your site.
The moth with the open and closed wing view looks like a Pandora Moth, Coloradia pandora, which can be found on BugGuide. There are several other very similar looking species in the same genus also found in Arizona, but our money is on the Pandora Moth.
