Fairly large syrphid. Compare this species with the previous photo of S. pyrastri. The yellow comma-shaped markings (on tergites 3 & 4) tapering towards the abdominal edge are characteristic of this species. Also notice that the inner and outer ends of these bars reach equally as far forward unlike S. pyrastri.
