I found this bug in a garden in Utah. The body was flattish, with teal markings (lighter than it looks in the photo) with an interesting pattern of three dots along the back, and a pink cone projecting down to the rear. It was about the size of my smallest fingernail.
From the searching I've done, the shape and the light "rim" on the outside of the shell look like a June Bug or a Stink Bug, but this one was not as green and the markings seem a lot more pronounced.
Is it a pest to be concerned about?
