2013-09-26, on fungus in a forest near Marburg, central Germany, about 2-3 mm sized. Is it a Amiota sp.? Regards, Ingo

Anthomyzidae, Paranthomyza nitida I think.

Thank you Dmitry for the identification and the correction of my error.
Greetings, Ingo

Leiomyza scathophagina (Asteiidae), I think.

Okay here is another photo. Sorry for the poor quality. The flies were very small, it was very dark in the forest and this is an extract from video frames only.

My two main reasons for not thinking it to be Paranthomyza nitida are the location (on fungus) and wing venation [apparently R4+5 and M are convergent towards the wing tip and cross vein r-m is placed proximally of where R1 jopins the costa, rather than distally].

Paul thank you for your explanation. Indeed I found all of them on colonies of fungi. But only a single fly was found per group of adjacent fungi (always males waiting for femals?). Last year you identified a gravid female of this species from nearly the some location (http://www.dipter...d_id=49948 ) feeding nectar on Impatiens. Lay females their eggs on these fungi also?

I think they are fungivorous.

Thanks. On 2013-07-14 I found the species on another species fungi too. So it looks for me they are not related to one special fungus species. Greetings, Ingo
