No, this is
Anasymia sp.
Helophilus stripes are always fairly bright orangey yellow.
Anasymia have pale grey stripes and very strongly curved comma shaped abdominal patterns.
Helophilus have different, more banded patterns. Again, I would have to look at my books to get to species level.

Thank you Susan.
My key isn't a fresh one, here Anasymia is still inside Helophilus.
According my key it is "subgenus" Anasymia, it is not Anasymia (H.) lineata, probably A. transfuga.

Try Mark van Veen's hoverfly key - I am fairly sure it is in English and on the web. I am not going to have time until tomorrow evening at the earliest to look up my key. [Just checked the downloads on this site - I was right - click on the download called Faunist]
Also, if Gerrard or someone sees this, I expect they will know it for sure.

This is Anasimyia interpuncta. It's not A. lineata because it doesn't have a long snout. It's not A. contracta or A. transfuga because these species have abdominal markings in the shape of hockey-sticks. A. lunulata is similar to A. interpuncta, but the markings on tergites 3 and 4 are less angled in that species.

Nope, sorry. Black, your fly is a
Anasimyia lineata. It has a longer face, almost a snout like in
Rhingia. As a quick field character it is also useful to note the colour difference. To me
lineata is a yellow&black fly with some grey parts, the other
Anasimyia species are grey & black with little yellow here and there.

Thanks a lot Jere, the snout's really much Rhingia-like.
