Moved from Syrphid Flies.

I think this is Eristalis stipator. The eyes are totally pale haired and obviously hairy and not so in E.dimidiata. The scutellum is obviously differently coloured from thorax but in E.dimidiata they are the same. The scutellum is too pale for E.dimidiata. The thin pale rim at the hind margin of each tergite is grey but is white in E.dimidiata. The markings on tergite 2 are chestnut, more orange in E.dimidiata. The scutum is obviously pale haired, not so in E.dimidiata from a STRAIGHT DORSAL view.
In E.dimidiata,at the base of the wing, the cell before the humeral cross vein is black or dark, contrasting with the rest of the wing but in this specimen the cell is clear like the rest of the wing. The basal half of the tibiae is white or very pale yellow in Eristalis dimidiata.

Bill you are completely right
Bill you are completely right... this is not dimidiata... I was too quick making this ID. You raised a lot of good points and I agree with your assessment!

Thanks, Martin.

Eristalis sp., a male.
Abdomen looks different than E. tenax, which has an hourglass shape ala:

Thank you, Ron.
