The second photo appears to show rather wide parafacials with numerous frontal setae. Only a guuess but this suggests Leucophora. The abdomen is rather cylindrical. I think the problem is that one needs to know the characters which will lead one to a genus or even a species, but most photographers don't know this, or they would be the experts! If you want to know what these are, download my keys. |

If you want to know what these are, download my keys. Many thanks! The problem is, that I am a layman, who has never worked with keys. In most cases I try to take photos from as many directions as possible, but sometimes this is difficult (especially if you don't know, which are important - as you noted). In these more difficult cases I'm even happy, if one of the experts can tell me the correct family.

I think it is very laudable that so many photographers are taking pics of flies, and encouraging others to do so. I am very happy to comment on all the Anthomyiidae. As all my work is directed to putting a specific name on specimens, you will appreciate that it is slightly frustrating when I can't turn the photo round under a binocular microscope, and even chop off the end of the abdomen and make a preparation of the genitalia. 99% of all male anthomyiids have distinctive genitalia, which means that one can have 20 specimens which all look the same externally, on dissection 5 different species turn up! |
