I was on Hydrangea arborescens. Sorry the pics aren't better --it was as close as I could get before it left.
Here is a link that might be useful:
Could if be a Great Spangled Fritillary?

or variegated fritilliary.
Beautiful, none the less!
It's a great spangled fritillary, another butterfly that made me want to move to those mountains of yours!
They're all so beautiful, Spaceman! Thanks, Laura and hey, Sherry :) I'm getting confused, though. On Laura's link the photo doesn't have the same sort of heart-shaped bottom as in my pic and that is on the link below.
It took me a while to see what you meant by 'heart-shaped bottom' but I think I now get it. The butterfly in Laura's link is undoubtedly just holding its wings differently. I see this all the time, especially with swallowtails - the way they position their wings makes a difference in their body shape. The heart shape probably happens when the wings are completely extended, and Laura's butterfly's wings weren't.
If you have a good field guide, you'll see that great spangled frits in the eastern part of the US look a little bit different than the ones out west, also the great basin individuals look a little different.
The only other butterfly that yours could possibly be is an aphrodite fritillary, but the markings on yours look like a GSF to me.
