Longhorn Beetle / Pseudogaurotina cressoni

This photo was taken on 23 June 2015, on a botany walk at Griffith Woods, off Highway 8 in Calgary. Whenever I am on a walk in the summer, I tend to check out wild roses in case I can find one of these beautiful, iridescent beetles. They are very small (10 - 14 mm), so are not easy to spot. I believe I have the correct ID, but would welcome any confirmation or correction - thanks! Will add a different, previously posted shot that was taken a long time ago, in a comment box below.
