About 30mm
This species looks superficially quite like Sphecius speciosus (the eastern cicada-killer wasp), but the abdominal banding is much less "ornate". These markings lack a hooked structure and are overall broader and smoother. The scutellum and postscutellum are also marked in yellow, unlike in S. speciosus.
