Hello, Theo and Maja!

First of all, M. umbellatarum is not an early spring species.
Secondly, M. quadrimacualata does not have comma-shaped markings, so your description does not fit.
Thirdly, hibernation of Scaeva pyrastri is quite unusual, whereas it is common in Sc. selenitica. At least in The Netherlands.

I think without a photo the identification of my early Syrphid will lead to no result and remain speculation. The only thing I know for sure, is that it was no Scaeva. This genus was one of the most abundant here last summer, and I know it quite well and took many photos:

I think those flies are all S. pyrastri, I never watched an undoubted S. selenitica here and never a Scaeva before May. Most of the photos above were taken from July to early September.
