Fritillaries can be found throughout North America.  They come in many forms.  Most have orange and brown colors; a number have silver markings under the wings.  This one found in Oregon's Steens Mountains lacks the silver markings but the simplicity of the underside pattern calls attention to the delicate vein structure.  These butterflies are most plentiful in rural areas and the wilderness.  When I was growing up we lived on the outskirts of a suburb and they were not very easy to find.  I collected butterflies as a hobby back then and it was exciting to catch one of these rare beauties.  Today I don't collect them to put in display cases, instead I take their pictures.  

When my brother found out about my butterfly photos, he said "At least you aren't killing them any more!"
