Just wanted to know the correct name of this bug. On the ground at Lands End, on the Grand Mesa, Grand Junction Colorado. During mid July, did not seem to be aggressive.

This little beauty is a female Sand Wasp in the tribe Bembicini, but we were not able to match your images to a species on BugGuide. According to BugGuide: “About three quarters of the species prey on Diptera, and it is believed that fly predation is ancestral in the group; the rest prey on Lepidoptera, Hymenoptera, Neuroptera, Odonata, and/or Homoptera.” The female provisions the underground nest with prey for the developing brood to feed upon, and as BugGuide states, most Sand Wasps prey upon flies.
