Hoverfly

One of the first hoverflies of this year for me: probably Eupeodes luniger (Diptera: Syrphidae), similar to Scaeva pyrastri but the yellow curved markings on its abdomen are yellow instead of white.  (Actually, the curved markings on E. luniger seem to vary quite a lot in both curvature and thickness, see here and here.)  The above specimen is probably a female, as is the following which I photographed a couple of weeks later:
