Hello,
The next fly of today's photo-shooting is rather small, grey, and has several spots on the wings. I hope it is recognizable...

Opomyzidae?

Opomyza florum?

Hi J?rgen,

It looks like Opomyza florum indeed. A very dark one. I've never seen such a dark specimen of O. florum. I would have loved to study this specimen in more detail, but I know you don't collect specimens. I have one seen a female whith a similar dark abdomen which proved to be O. florum. In that specimen the thorax was much more yellowish than in your specimen though. Still I think your identification is correct.

Dear Jan Willem,
I am not willing to abandon my fly to Juergen, it decided to stay in Berlin! Nevertheless it is interesting to learn that it is remarkably dark. Can that be a kind of "autumn colours"? (Several bugs turn dark in autumn.) And the colour-changing effect of the photoflash is also to be considered, but it was a grey afternoon, and I had to use it.
At least one thing Juergen and I have in common: we are no fly catchers. So I cannot send you the specimen. When I take photos of unknown animals, I cannot pre-estimate whether the specimen might be a sensational find or just a very common critter. Prophylactic killing, however, is not my cup of tea. I rather accept that a photo might remain without a name.
Many thanks to all for identification,
Sundew

Dear Sundew,

I didn't pay enough attention, I thought (I don't know why!) the photo was taken by J?rgen. Nevertheless, the outcome is the same, there is no collected specimen to be studied;). Your photo's are interesting though.
