Hello,
what kind of fly is this, with striped eyes and a metallic body? (found in Rhineland on the flower heads of Tanacetum vulgare. Size about 5mm)
Thanks,
Michael

It's from the family Lauxanidae. Probably Calliopum spp?

Thank you for your answer Nigel,
the fly looks indeed exactly as Calliopum simillimum in den gallery.

Most of the time pictures will not allow differentiation between
C. aeneum and
C. simillimum.

They seem to have flying season at the moment! See my thread
http://www.dipter...ad_id=9068 from yersterday. Today I photographed another one and clearly saw the striped eyes.

I found a specimen from last september on my harddisk, labeled Calliopum aeneum, parhaps not correctly. Here is it. What is the difference between those two species.

The usually given differences are only in male and female genitalia. There are, however, also differences in dusting on the face and the spines on the tibiae. None of these are visible in your image.

Paul,
I have a few specimens of Calliopum for id. Can you advise how to determine them? What references are there (if any) for this genus?
Any help gratefully received.
