Most likely arbustoum but could also be nemorum now I believe called E.interuptus

Eristalis

As WLR says, this is probably arbustorum.

As a male, though, the confusion species would not be nemorum (used to be interruptus), but abusiva, which also lacks the dark centre to tergite 2 stretching across to the margin. In male nemorum, that dark centre does stretch across, isolating the yellow spots at the side of the tergite. Females of arbustorum and nemorum can be very similar, though.
