Volucella inanis

This is V. inanis - they can be tricky to tell apart, but there was a useful article in the Hoverfly Recording Scheme newsletter by David Iliff some years ago pointing out that the most consistent topside difference is in the size and shape of the spots on tergite 2 (the first visible segment of the abdomen, nearest the thorax). In V. zonaria the spots are further forward, leaving a wider black band behind them, and the spots have curved hind edges in zonaria, whereas in V. inanis the spots are squarer and leave a narrower black band behind them.
