[UK] Do hoverflies make noises?

[matthewvosper]

Were their wings still moving when this sound was made? I wonder if the leaves were amplifying the vibration like a sounding board - or perhaps an effect of the downdraft of the wings on the leaves. If by ‘lanky’ you mean long-bodied then Sphaerophoria is perhaps an option. (Syrphus itself though fits the behaviour better, and they are quite buzzy)
