Helophilus pendulus? Tunstall Hills, Sunderland

Observation - Helophilus pendulus? Tunstall Hills, Sunderland. Description: I understand that this is Helophilus species because of the stripes on thorax. Unfortunately I was only able to take one photograph but ID notes look right for H. pendulus: Face stripe appears dark below antennae ( despite poor resolution on photograph).

I understand that this is Helophilus species because of the stripes on thorax. Unfortunately I was only able to take one photograph but ID notes look right for H. pendulus: Face stripe appears dark below antennae ( despite poor resolution on photograph). Cannot see hind tibia which is another distinguishing feature. Determiner ID would be very much appreciated. and where can I get additional information about wing markings for hoverfly species?
