I live in a rural area & saw the insect in the attached photo for the first time yesterday evening. Am hoping you can help to identify it.

Dear Cindy,
We believe the tufts at the tip of the abdomen of the individual in your image indicate it is a male in the genus
Efferia, possibly Efferia albibarbis based on this BugGuide image and this BugGuide image.  Robber Flies are important predators that often take prey on the wing.
