From my garden today. 9mm long.
Because of the curved M1 I think it is a member of the Muscinae, probably Morellia sp. because of the pattern on the scutum. Or could it be Graphomyia, which I think also has curved M1. I can take more photos if it would help.
Thanks, Peter

Morellia is correct.

Thanks Stephane. I guess the females are indistinguishable.

Females can be distinguished - simplex has hairs on edge of prosternum. hortorum and aenescens differ in the amount of anteroventrals on hind tibia.

Thanks John. I'll look for those features when I find another one.

... but to find these hairs requires some experience, not an easy character indeed.
