Thread subject: Diptera.info :: Small syrphid

Hello!
This syrphid was only about half the size of a
Syrphus and its stripes were nearly white. I photographed it today on a meadow in Ostwestfalen/Germany and have no idea about the species. Can anybody help me? Thanks in advance!
Addendum: Could it be
Parasyrphus macularis?

Hello Juergen,
Syrphus vitripennis can be quite small, and also the stripes can be very 'whitish'.
By the color of it's thorax it is very clear that it belongs in the genus Syrphus, and it's size and color leave only S. vitripennis!
Greetings,

But it was really
very small. The estimation of only half the size of a "normal"
Syrphus was no understatement! Unfortunately I don't have it on a picture with another
Syrphus, but with a
Phaonia (?), which had the size of a normal house fly. On the second picture the same
Phaonia individual is with an
Episyrphus balteatus which is normally smaller than a
Syrphus.

Difficult to see the legs... but it looks Parasyrphus to me. Possibly annulatus, but we cannot be sure. Gerard's suggestion might be right too... vitripennis can be very very small. Did it have a darkened facial knob or facial stripe?

Here is another picture, more from the front. Maybe that helps.

Yes, I am pretty confident it's annulatus.
Catch it next time and use the DJN Schwebfliegen-schl?ssel for positive identification without having to kill the flie, I'd say :p
