Can anyone help me with this one, seen yesterday near running water on umbellifer plant (hogweed). Size from memory - perhaps between 5-10mm? many thanks for any help!

It's a male, so the frontal shot will give relatively little additional information.

Someone has suggested Thereva nobilitata .... is this a possibility?

T. nobilitata is usually more distinctly yellow and black, this fly seems more greyish. But I do not know how variable T. nobilitata is in this respect. But I think this is a Thereva species.

Looks like nobilitata to me, but I have to say that I often find Thereva males very difficult to name, even with specimens
