I saw this Callicera on flowers of Allium porrum.
Spa, Belgium, 2004-07-27
Antennal segment 2 short, femora mostly black, all tibiae orange and the look of the hairs on scutellar disc make me think to C. macquarti but in Belgium I think there is only aenea, fagesii and rufa.
What do you think?

Using Speight's key on Callicera my result is also C. macquartii (also because of the lack of black hairs on the abd. tergites)

Maybe you would like to add your pictures to the Gallery? - Because I have seen that we do not have C. macqarti there yet.

Checking again all the pictures I’d taken, I saw that the size of the antennal segments do not match with those of macquarti.
Here are some pictures where the antennal segments are better visible. The antennal segment 3 is about as long as antennal segments 1+2 together so it can’t be macquarti which has antennal segment 3 twice as long as antennal segments 1 + 2 together.

I think it is a female of Callicera aenea because :
- femora extensively black
- mesoscutum completely dull with 4 longitudinal stripes of dusting extending to the scutellum and hairs on posterior margin of scutellum as long as the scutellum

Wout Opdekamp told me that the colour of the tarsi in aenea is much less dark than in my specimen.
He looked at all the aurata he has in his collection (>20 from different countries) and there is a little variation in the pruinosity and the length of the hairs.
He consulted Frank van de Meutter (another specialist of the Syrphidae) who confirmed the identification as aurata.
