Hello, I found this fly In mid-august in North Rhine-Westfalia, Germany
According to the antennae it should be C. fagesi, C. marcquarti or C. rufa.
Does C. rufa always has completly yellow legs?
I would be thankfil for some help.

Because of the following combination,I identified it as C. macquartii. Thanks to Meeno Reemer for some help.
- antennal segment 2 no more than half as long as antennal segment 1; antennal segment 3 twice as long as antennal
segments 1 + 2 together

- mesoscutum with longitudinal stripes of grey dusting
mediall, wings almost entirely covered in microtrichia,
legs with at least all femora mostly black and tarsomeres 3-5 of all legs black,

and

- Scutellar disc with many hairs no longer than antennal segment 1; hairs on general body surface orange to whitish yellow, straight; abdominal tergites almost without black hairs; all tibiae orange

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
