Had a quick search on Google last night, but it seemed that any time I spotted a blue dragonfly that looked like mine, there was no ID, just the name "blue dragonfly". Photographed when friends, Linda and Tony, and I were on the Artemisia trail, Yellowstone National Park. We were looking for the Morning Glory hot spring, but were unable to find it. Happy to see this beautiful insect, though - it was such a beautiful shade of blue.

Thanks to Art and uncle mike for the ID - Western Pondhawk - much appreciated!
