Dear Georgia Peach,
This is neither a wasp nor a fly, but it is a very successful wasp-mimic moth, and it is your namesake.  This is a female Peach Tree Borer,
Synanthedon exitiosa, a species with pronounced sexual dimorphism, which should be very evident upon viewing this excellent image of a mating pair of Peach Tree Borers from our archive.  The male and female look like they are completely different species.
