I don't yet know the ID of this small insect, but thought I'd post it in case anyone happens to know its name. I noticed it flying and landing repeatedly two days ago on a hike west of Longview, southern Alberta. The beautiful blue colour was what caught my attention : ) This is a zoomed, cropped image - was unable to get close to it : ) Later: thanks to Art (LeapFrog!) for the Great Black Wasp ID!
