This is a Thread-Waisted Wasp in the family Sphecidae, but we are having trouble identifying its species. It looks similar to individuals in the genus Sphex pictured on BugGuide, including the Great Golden Digger Wasp, but its abdominal color and white facial and thoracic markings are quite different. Perhaps one of our readers will provide assistance.
