Hello Forum,
a rather small fly. By means of the gallery, I decided for Opomyza petrei. Is that correct? Not? What else? Hagen, NRW, Germany, 10. September 2010, near beech forest, 150msm,
Best regards, Josef

Could be either
Opomyza germinationis or
G. petrei. Do you have other pictures with a better view on the abdomen?

It isn't my group, but I have to say that Mesnil didn't convinced me that
petrei is a good species :@
Anyway, without abdomen it is
germinationis, because Linnaeus was almost 300 years earlier! :@

Besides the difference in colouration of the abdomen (which "can" be a bit tricky), there are differences in the genitalia and in the hairs on the proepisternum.

I concur. Most of the
germinationis group I find, the markings on the abdomen are clear cut. One sometimes finds the odd specimen that is doubtful. There are very good genitalia illustrations in "Drake, C.M. 1993.
A review of the British Opomyzidae" that soon resolve any doubts.
