We posted a photo of a Robber Fly from Arizona a few years ago and we never properly identified it, however, it looks very similar to your specimen. While we do not consider your collection to be carnage, we wish you had taken better care of this magnificent creature that probably looked much more impressive while it was alive and trying to capture prey. We are posting both of your images because the overexposed image shows details that are absent in the darker shot.

Thanks Eric. We looked on BugGuide for Mydas Flies, but nothing came close to this coloration. Do you suppose they mimic Tarantula Hawks?
